Vacuum Dewatered Flooring (VDF) is a concrete flooring method that uses vacuum dewatering to remove excess water from freshly placed concrete, lowering the water-cement ratio and improving the concrete's properties. The concrete is placed conventionally, then vibrated and leveled before a vacuum pump and suction mat remove 15-25% of the water. This increases compressive strength and reduces shrinkage and cracking. Advantages of VDF include monolithic, shrinkage-free floors in large panels up to 100 sqm, very high strength, controlled finishes, and high daily output.

Various properties of hardened concrete can also be analyzed over time using smart sensor chips embedded in samples.
Shotcrete
Shotcrete is a concrete or mortar conveyed through a hose and pneumatically projected at high velocity onto a backing surface. It was invented in the early 1900s and has emerged as the preferred industry term to describe pneumatically applied concrete. There are two main processes - dry mix and wet mix. Dry mix involves pre-blended dry or semi-damp materials conveyed via air to the nozzle, while wet mix fully mixes all ingredients before projection. Shotcrete provides benefits over conventional concrete like density, homogeneity, strength, and ability to apply to any surface. It is widely used for rehabilitation of subway tunnels, domed roofs, highway culvert repair, and new concrete construction.
Self compacting concrete
Self-compacting concrete (SCC) was developed in Japan in the 1980s to achieve complete compaction without vibration. SCC flows under its own weight, fills formwork and passes through reinforced areas without segregation of ingredients. It consists of cement, fine and coarse aggregates, chemical and mineral admixtures. Superplasticizers and viscosity modifying agents provide workability and stability. Tests like slump flow, V-funnel, and J-ring evaluate filling ability, passing ability and resistance to segregation. SCC offers benefits of reduced labor, better compaction and surface finish compared to conventional concrete but requires more precise material proportions and quality control.

Scc by mlv prasad
Self-Compacting Concrete or Self Consolidating Concrete (SCC) is a highly flowable, stable concrete which flows readily into place, filling formwork without any consolidation and without undergoing any significant segregation. The use of SCC eliminates the need for compaction therefore saving time, reducing labor costs and conserving energy.Fresh SCC must possess the key properties including filling ability, passing ability and resistance to segregation at required levels. The filling ability is the ability of the SCC to flow into all spaces within the formwork under its own weight. Without vibrating the concrete, SCC has to fill any space within the formwork and it has to flow in horizontal and vertical directions without keeping air entrapped inside the concrete or at the surface. Passing ability is the ability of the SCC to flow through tight openings such as spaces between steel reinforcing bars, under its own weight. Passing ability is required to guarantee a homogenous distribution of the components of SCC in the vicinity of obstacles. The resistance to segregation is the resistance of the components of SCC to migration or separation and remains uniform throughout the process of transport and placing.

Industrial flooring by tremix vacuum system
The document describes industrial flooring using the Tremix vacuum system. It discusses the materials required, including a vacuum dewatering pump, floater machine, Tremix skin, and double beam screed vibrator. The concept involves using vacuum dewatering to remove excess water from freshly placed concrete, reducing the water-cement ratio and improving properties. The procedure involves laying guide rails, pouring and vibrating concrete, dewatering with a vacuum pump, floating, and final finishing. The Tremix system results in a stronger, higher quality industrial concrete floor.
Compaction of concrete
Compaction is the process of expelling air from freshly placed concrete to increase its density. It increases concrete's strength, bonding with reinforcement, and durability while decreasing permeability. Compaction can be done manually by rodding, ramming, or tamping, or mechanically by internal vibration using poker vibrators, external vibration of forms, or surface vibration of screed boards. Mechanical vibration is more efficient and allows placement in difficult areas with less water needed compared to manual methods. Proper compaction results in strong, dense concrete.

Testing shows that permeable concrete with an aggregate to cement ratio of 2.78:1 and 12.5mm coarse aggregates has a high coefficient of permeability of 0.271cm/sec while maintaining sufficient strength. The document concludes that mixtures using these parameters produce permeable concrete suitable for pavement applications.
Admixtures And Their Properties
This document discusses different types of admixtures used in concrete, including their uses and effects. It covers mineral admixtures like fly ash and silica fume that can reduce costs and improve properties. It also discusses chemical admixtures, specifically highlighting water reducers, superplasticizers, accelerators, and retarders. Water reducers and superplasticizers can lower the water-cement ratio while maintaining workability, leading to increased strength. Accelerators can reduce setting time while retarders have the opposite effect of delaying setting.
Unit-1 Lecture-2 - Light Weight Construction Materials by Brig. S.K. Sharma
This document discusses light weight construction materials, specifically foamed concrete. It describes four types of foamed concrete based on density and their typical uses. Densities range from 300-600 kg/m3 for thermal insulation up to 1200-1600 kg/m3 for precast panels. Advantages include economy, durability, thermal insulation, fire safety and wide range of applications. Disadvantages include reduced strength at lower densities and specialized tools needed for fastening. It also categorizes light-weight concretes based on aggregates and concludes that structural light-weight concrete combining strength and lightness will have economic advantages.

Ventilation Systems
Compared to commercial building, ventilation systems of warehouses are relatively simpler, but a warehouse brings with its own set of challenges as any design or structure would. Ventilation is critical for the warehouses because a lot of products are sensitive to temperature or humidity and dust and no consumer likes to get damaged or defective products.

Enabling Digital Sustainability by Jutta Eckstein
This is a New Zealand wide meetup event with meetup groups from Auckland, Wellington and Christchurch attending and open to anyone with an interest in digital sustainability or agile. All welcome. Joke, this is how it started. Jutta is now also available in Germany, i.e. hosted by Berlin/Brandenburg
According to the World Economic Forum, digital technologies can help reduce global carbon emissions by up to 15%. However, digitalization also comes with some challenges. Thus, if we want to make a positive impact by increasing sustainability, we need to address challenges like the digital divide, energy consumption of IT, or the rise of electronic waste. In this talk, I want to explore how Agile can help to leverage Digital Sustainability.

L'indice de performance des ports à conteneurs de l'année 2023
Une évaluation comparable de la performance basée sur le temps d'escale des navires
L'objectif de l'ICPP est d'identifier les domaines d'amélioration qui peuvent en fin de compte bénéficier à toutes les parties concernées, des compagnies maritimes aux gouvernements nationaux en passant par les consommateurs. Il est conçu pour servir de point de référence aux principaux acteurs de l'économie mondiale, notamment les autorités et les opérateurs portuaires, les gouvernements nationaux, les organisations supranationales, les agences de développement, les divers intérêts maritimes et d'autres acteurs publics et privés du commerce, de la logistique et des services de la chaîne d'approvisionnement.
Le développement de l'ICPP repose sur le temps total passé par les porte-conteneurs dans les ports, de la manière expliquée dans les sections suivantes du rapport, et comme dans les itérations précédentes de l'ICPP. Cette quatrième itération utilise des données pour l'année civile complète 2023. Elle poursuit le changement introduit l'année dernière en n'incluant que les ports qui ont eu un minimum de 24 escales valides au cours de la période de 12 mois de l'étude. Le nombre de ports inclus dans l'ICPP 2023 est de 405.
Comme dans les éditions précédentes de l'ICPP, la production du classement fait appel à deux approches méthodologiques différentes : une approche administrative, ou technique, une méthodologie pragmatique reflétant les connaissances et le jugement des experts ; et une approche statistique, utilisant l'analyse factorielle (AF), ou plus précisément la factorisation matricielle. L'utilisation de ces deux approches vise à garantir que le classement des performances des ports à conteneurs reflète le plus fidèlement possible les performances réelles des ports, tout en étant statistiquement robuste.

VDF- Vaccum Dewatered Flooring
- 1. EPA Infrastructure Pvt. Ltd. Vacuum Dewatered Flooring (VDF) B-267, North Ex Mall Sector-9, Rohini, Delhi-110085 Email: info@epa-infrastructure.com
- 2. What is VDF? The Vacuum Dewatered (VD) Flooring method, is a system for laying high quality concrete floors with superior cost-effectiveness. The key to the use of this method is the dewatering of concrete by vacuum process. Surplus water from the concrete is removed immediately after placing and vibration, reducing the watercement ratio to an optimum level.
- 3. Why is VDF preferred? Other Facts about VDF are as follows: Adopting the VD flooring method facilitates use of concrete with better workability than what is normally possible. A lowered water to cement ratio due to vacuum dewatering leads to improvement in each of the properties of concrete like wear resistance, compressive strength, less shrinkage and minimum water permeability. Through the vacuum treatment, it is possible to reduce the water content in the concrete by 15-25% which greatly increases the compressive strength. By lowering the water-cement ratio, the tendency of shrinkage and subsequent cracking is greatly reduced. Since the water-cement ratio is lowered through vacuum dewatering, concrete of high initial slump can be used while pouring.
- 4. Laying Method The method involves the laying of concrete in the following sequence: Concrete in the conventional way but with a higher slump so that the workability is good and concrete pouring and spreading is done fast. Poker Vibration (specially on both sides of the panel) is always essential for floor thickness of 100mm and above. Surface Vibration using Double Beams Surface Vibrator Leveling the vibrated surface with a straight edge. Vacuum Dewatering using Vacuum Pump and Suction Mat Top Cover & Filter Pads. Floating and Troweling of the concrete pavement using Skimfloaters.
- 5. Advantages The vacuum treated concrete floor/pavement, exhibits inherent advantages viz. Monolithic, Shrinkage free pavements. Single panel without joints upto 100 sq. meters (depending on design specifications) Very high splitting strength. Very high quality pavements in terms of strength of the pavement is increased giving flexibility to adopt wither leaner mix or design a slab of lesser thickness giving the required strength. Controlled and uniform surface finish. Very high output exceeding 100 to 200 sq. meters. in a day (depending on the configuration of Vacuum Dewatering System and other site conditions like concrete mixing and pouring speed).
