Production of concrete
The document outlines the key stages in the production of concrete: batching, mixing, transporting, placing, compacting, curing, and finishing. It describes the various methods used at each stage, including volume and weight batching, hand mixing and stationary mixers, transport using trucks and conveyors, placement using different techniques, compaction through hand tools and vibration, curing methods like immersion and membrane curing, and finishing concrete surfaces.
Self compacting concrete (scc)
Self-compacting concrete was developed in Japan in the 1980s to solve problems with inadequate compaction of traditional concrete. It uses a high paste content and superplasticizers to create a concrete that can flow and consolidate under its own weight without vibration. Tests were developed to evaluate properties like filling ability, passing ability, and segregation resistance. Self-compacting concrete provides benefits like easier placement, faster construction, better surface finish, and improved durability. However, it also has higher costs associated with materials and mix design development.
Study on properties of concrete by partially replacing cement with GGBS
India has an enormous growth in the industry of steel and copper. These industries produce hazardous by products like ground granulated blast furnace slag (GGBS). If they were not disposed off properly, they may cause hazards to the atmosphere. Considering the long term performance and stability of structures, this study suggests replacing some percentage of cement withGGBS to develop high performance concrete. This paper presents an experimental investigation to know the use of GGBS in concrete as a replacing agent of cement.. To accomplish this 53 grade Ordinary Portland cement were used in preparing concrete mix with a w/c ratio of 0.40 with suitable superplasticizers. In order to confirm the use of GGBS as a replacing agent tests were conducted. Cement was replaced with 0% to 40% with GGBS respectively. Concrete control specimens without replacement were also cast for comparison. After casting the cube moulds specimens were tested for various tests likecompressive strength test, tensile strength test, flexural strength test.
Bituminous mix design
1) The document describes the process for Marshall stability test and mix design for bituminous concrete. Key steps include selecting aggregates based on strength and gradation, determining aggregate proportions, preparing specimens, and testing stability and flow.
2) Aggregate proportions are determined using an analytical method solving equations for the required gradation. Specimens are compacted and tested for stability (maximum load) and flow (deformation) at varying bitumen contents to determine the optimum mix.
3) Stability and flow values are measured using a Marshall test machine and calculations are done to determine density, voids, and other properties of the mix. The process is repeated to get the optimum bitumen content for the mix design.

EXPERIMENTAL STUDIES ON PROPERTIES OF GEOPOLYMER CONCRETE WITH GGBS AND FLY ASH
Objective: This paper manages the quality properties of geopolymer concrete. The primary point of this anticipate is to utilize ground granulated impact heater slag and fly fiery remains set up of common Portland concrete, keeping in mind the end goal to decrease carbon dioxide emanation. Method: From this, we can look at the properties of geopolymer concrete with bond concrete. The fixings utilized as a part of this anticipate are GGBS and Fly cinder. Sodium hydroxide and sodium silicate are utilized as basic activators. The molarity of sodium hydroxide is 8M and 10M. The proportion of soluble activators is 1:2. Calcium silicate is framed when GGBS gets responded with sodium hydroxide and sodium silicate. This calcium silicate goes about as a cover for coarse total and fine total. Findings: The response is said to be exothermic since the warmth is developed when calcium silicate is framed. Henceforth, the underlying warmth is not required to begin the polymerization procedure. The fly fiery remains and GGBS are supplanted in 5 distinctive extents (100% GGBS, 75% GGBS &25% Fly cider, half GGBS &50% Fly slag, 25% GGBS&75% Fly powder,). The curing is finished by putting examples at room temperature. Application: The examples are tried at 7 years old and 28 days, the test incorporates compressive quality, split elasticity, and flexure quality to contrast the outcomes and bond concrete.
Flow test of concrete
This document describes a flow test conducted to measure the workability of concrete. The test involves filling a slump cone with concrete, raising the cone to allow the concrete to spread across a flow table, and dropping the table 15 times. The average diameter of the spread concrete is then measured. The student conducted the test and found the average diameter was 565mm, within the acceptable range of 400-650mm for flowing concrete. The flow test is concluded to be a useful method for measuring the workability of high-slump concrete in both lab and field settings.

The document provides details on mix design methods for bituminous concrete like Marshall and Hveem.
CERAMIC WASTE CONCRETE
A ceramic is an inorganic compound, non-metallic, solid material comprising metal, non-metal or metalloid atoms primarily held in ionic and covalent bonds. This article gives an overview of ceramic materials from the point of view of materials science.
The crystallinity of ceramic materials ranges from highly oriented to semi-crystalline, vitrified, and often completely amorphous (e.g., glasses). Most often, fired ceramics are either vitrified or semi-vitrified as is the case with earthenware, stoneware, and porcelain. Varying crystallinity and electron consumption in the ionic and covalent bonds cause most ceramic materials to be good thermal and electrical insulators (extensively researched in ceramic engineering). With such a large range of possible options for the composition/structure of a ceramic (e.g. nearly all of the elements, nearly all types of bonding, and all levels of crystallinity), the breadth of the subject is vast, and identifiable attributes (e.g. hardness, toughness, electrical conductivity, etc.) are hard to specify for the group as a whole. General properties such as high melting temperature, high hardness, poor conductivity, high moduli of elasticity, chemical resistance and low ductility are the norm,[1] with known exceptions to each of these rules (e.g. piezoelectric ceramics, glass transition temperature, superconductive ceramics, etc.). Many composites, such as fiberglass and carbon fiber, while containing ceramic materials, are not considered to be part of the ceramic family.[2]
Mix design of concrete
The process of selecting suitable ingredients of concrete and determining their relative amounts with the objective of producing a concrete of the required, strength, durability, and workability as economically as possible, is termed the concrete mix design.
Tests of aggregates
This document provides information on various tests conducted on aggregates that are used in construction. It describes the aggregate abrasion value test, which determines the abrasion resistance and hardness of aggregates. It also summarizes the aggregate impact value test, which evaluates the resistance of aggregates to shocks and impacts, and the aggregate crushing value test, which determines the resistance of aggregates to crushing under gradually applied compressive loads. Finally, it outlines the procedure to determine the specific gravity and water absorption of aggregates.
Rubber concrete
This document studied the effect of adding waste rubber to concrete. It conducted tests with concrete mixtures replacing the coarse aggregates with 5%, 10%, 15%, 20%, 25%, 30%, 50% and 100% rubber by volume. The results showed that as the percentage of rubber replacement increased, the compressive strength, slump, and density of the concrete decreased. However, adding rubber improves the concrete's elasticity and deformation properties while providing an environmentally friendly way to dispose of waste tires. The study concluded that rubberized concrete is most suitable for applications not requiring high strength, such as concrete pavements.
Self curing concrete using peg
The document discusses the use of self-curing agents like water soluble polymeric glycol in concrete. Self-curing concrete cures itself without external water by absorbing moisture from the atmosphere. The study aims to determine the optimum dosage of polyethylene glycol (PEG) as a self-curing agent under different curing conditions. PEG is added to concrete mixes to increase the density of water and reduce evaporation during curing. Test results show that concrete cubes cured with PEG have higher compressive strength of 33MPa compared to 28MPa for water-cured cubes after 28 days. The document concludes that self-curing concrete addresses issues with lack of proper curing.
