Why is concrete such a widely used construction material?
Concrete is the most used material throughout the world, mainly thanks to its durability and strength. Concrete can handle almost ever climate and is resistant to erosion, rotting and rust- meaning that it requires minimal maintenance. Concrete can outlast wood and other common building materials and its strength improves over time.
What materials are required for concrete?
The principal ingredients that make up the concrete mix are: cement, fine aggregate, coarse aggregate, water, chemical admixtures, and mineral admixtures. Concrete used in construction may also contain reinforcing bars, welded wire fabric (wire mesh), and various reinforcing fibers.
What are three main materials in concrete?
Concrete is a composite material consisting of a binder, which is typically cement, rough and fine aggregates, which are usually stone and sand, and water. These comprise the constituent materials of concrete.
What is the most important materials used in concrete?

What is the best SCM for cement?
Fly ash is the most common SCM and it improves finishability, although it tends to slow the set time, especially in cold weather. SCMs can be used to replace as much as 40% of the cement in a mix. Slag and metakaolin lighten the color of concrete which can be beneficial with integrally colored concrete. Metakaolin also helps to reduce the danger of efflorescence.
How to reduce shrinkage of concrete?
With our goal of reducing shrinkage though, aggregate becomes critical. To reduce shrinkage, we need to reduce the total amount of cement paste in the mix— the aggregate doesn't shrink. To reduce the cement paste, we need to minimize the spaces between the aggregate particles. That is accomplished with a "well-graded" aggregate mixture that starts with the largest aggregate size possible—ideally 1 ½ inches, although it should be less than 1/3 of the slab thickness and few stamping contractors will want to stamp a mix with aggregate that large. "I specify ¾ inch," says Bob Harris of the Decorative Concrete Institute. "Most of our stamp mixes are somewhere around ½ inch top size aggregate, but if we're pouring thick concrete we can successfully stamp ¾ inch or #57 stone."
What is the last ingredient in concrete?
One last ingredient in many concrete mixtures today is supplementary cementitious materials (SCM)--also called pozzolans. These materials include fly ash, slag cement (sometimes called ground granulated blast furnace slag—GGBFS or slag cement), silica fume, and metakaolin. SCMs are used as replacement for cement, and since they have a very small particle size, they reduce the permeability of concrete, which is good.
What is SCC in construction?
SCC is also ideal for producing glassy surfaces on sculpture, furniture, or countertops. Retarders and accelerators are also useful admixtures, especially when dealing with the variations in set time from cold or hot temperatures. One technique every decorative contractor should understand is set retardation (see Concrete Construction, July 2002, ...
What is a water reducer?
Water reducers can be used to maintain a specific slump with less water—reducing water content up to 30% or even turning concrete into self-consolidating concrete (SCC) that has a soupy consistency that is very useful for detailed decorative walls or when you want concrete to flow easily around embedded objects or congested reinforcing steel. SCC is also ideal for producing glassy surfaces on sculpture, furniture, or countertops.
What are the components of concrete?
What components go into the mix? Cool Climate Concrete. We all know that concrete is primarily portland cement, aggregate, and water. And in general it's best to keep it simple, since more ingredients can make it more difficult to control.
Does a low W/C ratio reduce shrinkage?
In that article he noted that a low w/c ratio "may increase strength and improve durability, but it is not likely to reduce shrinkage." He recommends lowering the total water content and even the cement content to reduce shrinkage, even if it means that the w/c goes above 0.5. Although this article was written specifically for industrial floors, it's wisdom applies equally to decorative floors.
What should be used for cement concrete?
The aggregates to be used for cement concrete work should be hard, durable and clean. The aggregates should be completely free from lumps of clay, organic and vegetable matter, fine dust, etc. The presence of all such debris prevents adhesion of aggregates and hence reduces the strength of concrete.
What is broken stone used for?
The broken stone is generally used as a coarse aggregate. The nature of work decides the maximum size of the coarse aggregate. For thin slabs and walls, the maximum size of coarse aggregate should be limited to one-third the thickness of the concrete section. The aggregates to be used for cement concrete work should be hard, durable and clean.
How are igneous rocks formed?
The igneous rocks are formed originally by cooling from a molten rock material known as magma. They are further classified as plutonic rocks, hypabyssal rocks and volcanic rocks. The plutonic varieties are brittle due to the presence of large crystals and the main types of rocks under this variety are granite, syenite, diorite, etc.
How are sedimentary rocks formed?

What is natural aggregate?
The term natural aggregate is used loosely to designate aggregates which need only be removed from their natural deposits as unconsolidated sediments. The aggregates obtained from such deposits are called gravel and sand while those produced from ledge rock, boulders or cobble stones are known as crushed stone.
Why are dolomites and lime stones used?
The lime stones and dolomites are suitable because they have excellent adhesion to cement and bituminous binder. The chalk is unsuitable for construction purpose.
Why do you add admixtures to concrete?
It may be noted that sometimes the ingredients other than above are added in concrete to give it certain improved qualities or for changing different physical properties in its fresh and hardened stages. These ingredients or substances are known as the admixtures. The addition of an admixture may improve the concrete with respect to its strength, hardness, workability, water-resisting power, etc.
How to calculate concrete volume?
The formula for calculation of materials for required volume of concrete is given by: Where, V c = Absolute volume of fully compacted fresh concrete W =Mass of water C = Mass of cement Fa = Mass of fine aggregates Ca = Mass of coarse aggregates S c, S fa and S ca are the specific gravities of cement, fine aggregates and coarse aggregates respectively. The air content has been ignored in this calculation. This method of calculation for quantities of materials for concrete takes into account the mix proportions from design mix or nominal mixes for structural strength and durability requirement. Now we will learn the material calculation by an example.
