Types of cement. Cement is a binding material used to bind different type of construction materials together. It is formed from argillaceous, siliceous, calcareous etc. By twisting this internal mix ratio and by altering the chemical inputs, special types of cement can be produced according to the needs.
In concrete technology, a variety of type-names has been used for different types of concrete. This classification is based on three factors: 1. Type of material used in its making. 2. Nature of stress conditions. 3. And it's density.

This type of concrete is often used as a quick fix for weathering for loose soil types in construction zones. There are two application methods for shotcrete. dry-mix – the dry mixture of cement and aggregates is filled into the machine and conveyed with compressed air through the hoses. The water needed for the hydration is added at the nozzle.
This types of cement is widely used for decorative works in floors and ceiling. Coloured cement is commonly used in grouting of tiles. The cement is selected such that the colour of the grout and colour of tiles match perfectly for finishing the flooring. Also Read: Basics of .
Most commonly, regular concrete is created by mixing Portland cement with both an aggregate and water-chemical mixtures. Often times, cement and concrete are incorrectly interchanged: concrete is the hard, rock-like substance that is so frequently seen in urbanized areas. Cement is an ingredient, the powder, used in the creation of concrete.

We know that In a mortar, we use fine aggregate and in concrete, we use coarse aggregate for the building purpose.These are the main classification of aggregate that is used in civil engineering studies.But we will discuss other types of aggregate also.Let's see. Types of Aggregate
Construction documents often specify a cement type based on the required performance of the concrete or the placement conditions. Certain cement manufacturing plants only produce certain types of portland cement. What are the differences in these cement types and how are they tested, produced, and identified in practice?
Type III portland cement is a high-early-strength concrete; it sets in a week or less. It's used where the structure must be completed quickly, or to reduce curing time in cold weather. Type IV is a low heat of hydration cement, used for massive concrete structures, such as gravity dams, where heat isn't released from the mass.
