Plastic shrinkage cracks occur when the surface of fresh concrete dries too quickly due to rapid evaporation before the concrete has set, causing the surface to shrink more than the interior. This develops tensile stresses that can exceed the concrete's strength and cause cracking. The risk of plastic shrinkage cracking can be reduced by protecting fresh concrete from direct sun and wind, using a low-slump mix with fine sand, applying curing compounds to prevent evaporation, and timing concrete placement to avoid rapid drying conditions. Proper curing is important to ensure the surface evaporation potential is zero and prevent further cracking.

Self healing concrete by Azlan Ahmad
Self-healing concrete uses bacteria and calcium lactate to autonomously repair cracks up to 0.5mm wide. When water enters cracks, bacteria metabolize calcium lactate to produce limestone that fills the cracks. Tests show self-healing concrete has higher compressive and flexural strength than normal concrete, and is more durable and crack-resistant. While more expensive initially, self-healing concrete reduces long-term maintenance costs by preventing corrosion and extending structure lifespan. Current research focuses on optimizing bacterial and nutrient encapsulation to ensure reliable self-healing.
Self healing concrete
Self-healing concrete has the ability to automatically repair cracks without external intervention. It exists as a spray, mortar, or within the concrete mixture. Cracks are inevitable in concrete over time due to loads and deterioration. Self-healing concrete helps prevent further cracking through two main mechanisms: bacteria that precipitate minerals to fill cracks or capsules containing chemicals that bond when cracks form. While initial costs are high, it reduces long-term maintenance. The concrete has improved durability, permeability and applications in infrastructure but bacteria use remains costly and strength increases slowly.

Cement concrete.pptx
Cement concrete is a composite material consisting of a binding material (cement or lime), aggregates (fine and coarse), water, and admixtures. The cement and water form a paste that coats the aggregates and binds them together. Concrete can be classified based on its constituents, method of production, place of casting, and bulk density. Proper curing is important for concrete to gain strength and hardness through hydration. Common curing methods include water curing, membrane curing, and steam curing. The water-cement ratio significantly impacts concrete strength, with lower ratios producing stronger concrete.
Concrete
Concrete is a composite material made of aggregates, sand, cement and water. It has many useful properties such as versatility, durability and fire resistance which make it widely used in construction. Fresh concrete must have adequate workability and consistency to be properly mixed, placed and consolidated. Proper curing is also important to allow the cement to fully hydrate and gain strength over time. While concrete has advantages, it also has disadvantages like low tensile strength and requires careful mixing to ensure uniformity.
Creep and shrinkage
This document discusses creep and shrinkage in concrete structures. It defines creep as time-dependent deformations of concrete under load, and shrinkage as shortening of concrete due to drying that is independent of applied loads. Factors that affect creep include concrete mix proportions, aggregate properties, age at loading, curing conditions, cement properties, temperature, and stress level. Factors that affect shrinkage include drying conditions, time, and water-cement ratio. The document also discusses types of shrinkage such as plastic, drying, autogenous, and carbonation shrinkages. It outlines effects of creep and shrinkage on structures and methods to prevent shrinkage.
Curing of concrete
Curing concrete is important to allow the cement hydration process to continue and develop strength over time. Proper curing ensures concrete reaches its designed strength and durability by controlling moisture loss. Common curing methods include water curing through ponding, sprinkling or wet coverings; membrane curing using plastic sheeting or curing compounds; and steam curing to accelerate strength gain. Curing should continue for at least 7 days for normal concrete and 14 days if blended cements are used. Inadequate curing can lead to reduced strength, increased permeability and poor durability.

The document discusses various concrete surface defects including dusting, scaling, and crazing. It provides explanations of what causes each defect, how to prevent it, and how to repair surfaces affected by the defect. For dusting, the key points are to use moderate slump concrete, not finish when bleed water is present, cure adequately, and seal surfaces. For scaling, the document recommends using air-entrained concrete, avoiding deicers for one year, and sealing surfaces. It also provides tips on how to prepare surfaces for repair.
Shrinkage of concrete
The document discusses the different types of shrinkage that can occur in concrete, including plastic shrinkage, drying shrinkage, autogenous shrinkage, and carbonation shrinkage. Plastic shrinkage causes cracks on the surface of fresh concrete due to evaporation before setting. Drying shrinkage is defined as the contraction of hardened concrete from the loss of capillary water, which can lead to cracking, warping, and deflection without any external loading. In summary, the document outlines the main types of volume changes and shrinkage that concrete undergoes both during the plastic and hardened states.
Self-Curing-Concrete (1).pptx
Curing is maintaining moisture and temperature in concrete to allow hydration and development of properties. Proper curing increases strength, durability, and resistance to damage. Self-curing concrete uses compounds to retain mixing water and allow continued hydration without external curing. Membrane-forming compounds form a film on the surface to prevent water loss. This allows concrete to cure in places where water curing is not feasible.
Self curing-concrete-
Self-curing concrete is achieved by means of replacing a part of aggregate by lightweight aggregate or adding chemical admixtures. The self-curing process of concrete takes place from inside to outside, thus reducing the autogenous shrinkage and self-desiccation, especially for the high-performance concrete with relatively low water/binder ratio.

Cracks in-buildings
This document discusses various types and causes of cracks in buildings. It classifies cracks as either structural or non-structural and further categorizes them based on their width. Common causes of cracks include moisture movement, thermal variation, excessive loading, and foundation settlement. Plastic shrinkage, bleeding, delayed curing, and use of poor quality materials can lead to cracks in concrete before it hardens. Thermal expansion and contraction from temperature changes is another major cause of cracks. Various remedial measures are proposed to prevent or reduce cracking in structures.
Properties of fresh and Hardened Concrete
The document discusses various properties of fresh and hardened concrete. It describes workability, consistency, segregation, bleeding, mixing, placing, consolidating, and curing of fresh concrete. It also discusses compressive strength, tensile strength, modulus of elasticity, permeability, and durability of hardened concrete. The key properties of fresh concrete include workability, consistency, segregation, bleeding, setting time, and uniformity. Compressive strength is identified as the most important property of hardened concrete.
Self curing-concrete-civil
Curing is maintaining moisture and temperature in concrete to allow hydration and development of properties. Proper curing increases strength, durability, and resistance to damage. Self-curing or membrane curing uses compounds that form a film to retain moisture in concrete without external water. These compounds are hydrophobic molecules that form a monomolecular film to reduce evaporation and allow internal hydration, improving concrete properties where external curing is not possible. Application procedures and different compound types were discussed.
apresentationonconcrete-181109185836.pptx
Concrete is a composite material made from aggregates, sand, cement, and water. It has high compressive strength but low tensile strength. Freshly mixed concrete must have adequate workability and consistency to be easily transported and placed, which depends on factors like water content, temperature, and use of chemical admixtures. Workability is often measured using the slump test. Improper mixing or placing can cause issues like segregation, bleeding, or honeycombing. Curing plays an important role in hydrating the cement and improving the properties of hardened concrete. Compressive strength is the most important property of hardened concrete, as it is indicative of load-bearing ability and related properties.
Durability of Concrete
Durability is the ability of concrete to resist weathering actions, chemical attacks, and abrasion while maintaining its desired engineering properties. A durable concrete structure withstands deterioration over its design life through exposure to the environment. Factors that influence durability include the water-cement ratio, cement content, cover thickness, type of aggregates used, and curing of the concrete. Permeability is an important indicator of durability, with lower permeability reducing susceptibility to chemical attacks. Proper compaction and curing help reduce the permeability of concrete.

Comprehensive Guide to Balcony Waterproofing Repairs
Addressing Leaking Balconies, Roofs, and Rooftop Terraces
Leaking balconies, roofs, and rooftop terraces can cause catastrophic damage to structures below. Water leaks may cause not only aesthetic and superficial damage but can also compromise the structural integrity of the building envelope. If a failed waterproofing membrane is the cause, re-grouting or surface sealing is merely a temporary fix. Such band-aid methods will eventually fail, causing cracks in tiles, grout, and membranes as the balcony moves.
In many cases, failed membranes require a complete strip-off, structural repairs if needed, reinstallation of waterproofing, and a new finish surface. Key considerations in this process include the strength of the subfloor and screed, presence of substrate dips and hollows, correct balcony slope and fall, window and door frame installation, door threshold sealing, adequate drainage, and the potential for underlying pipe leaks. Existing tiling and expansion joints should also be assessed to determine their role in the balcony failure.
Waterproofing Preparation
Proper preparation is critical for any waterproofing membrane installation. The substrate must be clean, free of dirt and other contaminants. This involves vacuum cleaning and/or diamond grinding to ensure a smooth, dry, and debris-free surface. In some cases, washing the substrate may be necessary.
Waterproofing Detailing
Before installing a waterproofing system, construction features that interrupt the membrane layer must be adequately protected and sealed. This includes:
Perimeter Upturns: Attachment points for railings and balustrades, joints between horizontal and vertical surfaces, and structural and expansion joints. Sealant should be applied 15mm wide to all junctions, reinforced with polyester or fiberglass mat to a DFT of 1.2mm, 100mm above finished floor height, or 25mm above the water line. The membrane system should be installed 200mm onto balcony floor areas.
Door/Window Step Downs: Similar to perimeter upturns, apply sealant 15mm wide to all junctions, reinforced with fiberglass mat to a DFT of 1.2mm, ensuring the membrane system is installed 200mm onto balcony areas.
Drains & Floor Waste Details: All floor wastes should have a recessed leak control flange installed, primed with appropriate primer, and the membrane system installed as per specifications.
Waterproofing Installation: Australian Standards
The installation of a Class 2/3 waterproof membrane system to external concrete must comply with AS 4654.2. Key considerations for installation include:
Installation Conditions: Avoid installation in extreme temperatures (below 10°C or above 35°C) to prevent accelerated or decelerated cure times.
Type of Membrane: Use a flexible waterproofing membrane capable of withstanding normal cyclic fluctuations and ponding water.Findlay Evans Waterproofing with AIW - Article August 2017
Findlay Evans Waterproofing with AIW - Article August 2017MELBOURNE Commercial Waterproofers - Findlay-Evans Waterproofing
Waterproofing Changes in Victoria
The Building Act 1993 remains, but the Building Regulation 2006 will be replaced by the Building Regulations 2017, expected to be legislated around September. Key changes affecting the waterproofing industry include Part 13, which mandates inspection prior to covering a waterproofing membrane in any wet area.
The regulations remain consistent in other areas affecting waterproofing, such as the adoption of the NCC and relevant Australian Standards, methods of assessment of compliance, material testing, and compliance certificates.
The VBA confirms that only a registered Building Practitioner can authorize compliance of waterproofing works. Subcontractors who are not registered cannot authorize compliance. Although they can state that they have complied with the relevant standards, liability lies primarily with the registered builder, now shared with the Building Inspector or Surveyor for wet areas.
QBCC Tradie Tours
Waterproofing is consistently one of the most common defects reported to the QBCC, with mistakes being costly. In June 2017, the QBCC presented ten waterproofing seminars throughout Queensland, dedicated to waterproofing and tiling issues with a focus on preventing waterproofing defects. Approximately 1000 builders, waterproofers, certifiers, and tilers attended these seminars.
Bayset’s Training & Quality Manager, Frank Moebus, provided in-depth information about avoiding installation problems. The Tradie Tour received positive feedback from the industry.

Gary Moody, project manager, described the project as challenging but rewarding due to the successful outcome achieved by the experienced applicator.
Importance of Waterproofing Standards and Compliance
Legislative Changes and Their Impact
The introduction of the Building Regulations 2017 brings significant changes to the waterproofing industry, particularly regarding inspection and compliance requirements. For the first time, building inspectors or surveyors must inspect waterproofing membranes before they are covered in any wet areas. This change emphasizes the importance of thorough inspections to prevent defects and ensure high-quality waterproofing.Alauddin Trust | Charity Empowering People in Need

The AIW Delivers on the Importance of Waterproofing
On March 29, 2017, the AIW attended and presented at the ADEB (Architects Designers Engineers Builders) Waterproofing Breakfast Seminar in Sydney. The focus was on addressing commercial waterproofing and residential high-rise waterproofing failures and solutions.
Presentations and Key Points
Paul Evans, AIW President, gave an overview of the AIW's role in raising waterproofing standards in Australia. Robert McDonald, an AIW member, delivered a session on the “Australian Standards in Waterproofing.” These presentations covered:
Common defects in internal and external waterproofing
Priming and substrate moisture content
Inspection and testing of waterproofing
Drainage and waterproofing techniques
Product knowledge and standards compliance, including:
CA 55 - 1970 (Design and Installation of Bituminous Fabric Roofing)
AS 3740 (Waterproofing Wet Areas in Residential Buildings)
AS 4858 - 2004 (Wet Area Membranes)
AS 4654 - 2012 (Waterproofing Membrane)
The AIW remains dedicated to updating, providing current information, and educational resources for all industries involved with waterproofing.
Achieving Uniform Waterproofing Compliance Nationally
Achieving uniform waterproofing compliance across Australia involves collaboration with State and Territory Regulatory Authorities, which play a crucial role. Current licensing requirements are often disjointed, and in many states, not mandatory.
Local authorities and building surveyors request Waterproofing Application Certificates to certify compliance with BCA and Australian Standards. These certificates must be issued by a competent person, whose work falls under the scope of their license or who has formal qualifications to carry out the work. Training and qualifications are regulated under the National Qualifications Framework.Best CRH Sustainability online available

Plastic shrinkage cracks
- 1. PLASTIC SHRINKAGE CRACKS - HIMANSHU POONIYA
- 2. CAUSES OF FLOOR & SURFACE CRACKS…! • Cracks occurs in a material when the tensile stress applied is more then its tensile strength. • Concrete has a low tensile strength & undergo large volume change – swells in wet & shrinks as it dries • Volume of Hydrated Cement Paste – sensitive to its moisture content, controlled by RH of environment. • Shrinkage Component in concrete is cement paste. • Degree of Shrinkage – W/C, Age & Environmental Condition.
- 4. CRACKS Plastic Shrinkage Cracks FRESH CONCRETE Plastic Settlement Cracks HARDEND CONCRETE Drying Shrinkage Cracks
- 5. PLASTIC SHRINKAGE CRACKS • Plastic Shrinkage Cracks are caused by a rapid loss of water from the surface of concrete before it has set. • The critical condition exists when the rate of evaporation of surface moisture exceeds the rate at which rising bleed water can replace it. • Surface Water evaporation faster then bleed water-surface shrink more than the interior concrete. • As the interior concrete restrains shrinkage of the surface concrete, stresses that exceed the concrete’s tensile strength development, resulting in surface cracks.
- 7. EFFECT OF BLEED WATER IN PLASTIC SHRINKAGE CRACKS • In order to insure Plastic Shrinkage Cracking, make sure there is no bleed water. • Bleed Water is a direct function of total surface area in the mix: Most Surface Area Less Bleed Water Less Surface Area More Bleed Water
- 8. CONCRETE IN PRACTICE “If Plastic Shrinkage Cracks appear during final finishing, the finisher may be able to close with striking each side of the crack with a float refinishing, can close the crack”
- 9. PREVENTIONS OF SURFACE CRACKS…! • Protect from direct sunlight & wind, by plastic cover or start early Curing. • Do not use sand which lack fines. • Keep Low Slump. • Uses of Water Retarders Agents However, when this occurs, precautions as described below, should be taken to avoid further cracking:-
- 10. CURING: (2ND STAGE OF PREVENTIONS OF SURFACE CRACKS) A good curing system makes sure that the evaporation potential of the surface of the concrete is 0.0
