Concrete Information

Concrete is used more than any other man-made material in the world. As of 2006, about 7.5 cubic kilometres of concrete are made each year—more than one cubic metre for every person on Earth. Concrete powers a US $35-billion industry which employs more than two million workers in the United States alone. More than 55,000 miles (89,000 km) of ...


The cement itself can either be a pure hydraulic cement or a mix of hydraulic cement and SCM. Concrete mix recipes vary, but most have compositions (in volumetric terms) in the range of about: 7%–15% cement powder, 15%–20% water, 0.5%–8% air, 25%–30% fine aggregates (e.g., sand), and 30%–50%


Manufacturing - the cement kiln. Most Portland cement is made in a rotary kiln. Basically, this is a long cylinder rotating about its axis once every minute or two. The axis is inclined at a slight angle, the end with the burner being lower. The rotation causes the raw meal to gradually pass along from where it enters at the cool end, to the ...

Cement production in India has increased at a CAGR of 8.1 per cent during the last decade with a production level of 117.5 million tonnes in 2003-04. The cement industry comprises 125 large cement plants (capacity more than 0.198 million tonnes per annum) with an installed capacity of 148.28 million tonnes and


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.


Cement is produced in more than 150 countries all over the world. Cement, as the most important ingredient of concrete, is essential in the development of infrastructure and construction in general. The level of advancement in cement and concrete Supply Chain Management (SCM) can facilitate or constrain world economic development.


The per-ton cement cost at such a plant is between $35 and $40. This future is not far off. Our analysis shows that pursuing digitization and sustainability levers are key to significantly boosting productivity and efficiency of a typical cement plant (Exhibit 1). The result is a margin gain of $4 to $9 per ton of cement, 2.


Portland-limestone cement (PLC) is relatively new to the US, but has been used internationally for many decades in all aspects of concrete construction. PLC is a blended cement that incorporates between 5% and 15% limestone as an ingredient, which lowers its environmental footprint by about 10%.

Concrete - Wikipedia

Concrete is a composite material composed of fine and coarse aggregate bonded together with a fluid cement (cement paste) that hardens (cures) over time. Concrete is the second-most-used substance in the world after water, and is the most widely used building material. Its usage worldwide, ton for ton, is twice that of steel, wood, plastics, and aluminum combined.


Composition of cement. Introduction Portland cement gets its strength from chemical reactions between the cement and water. The process is known as hydration.This is a complex process that is best understood by first understanding the chemical composition of cement.

Introduction to Concrete

The term concrete refers to a mixture of aggregates, usually sand, and either gravel or crushed stone, held together by a binder of cementitious paste. The paste is typically made up of portland cement and water and may also contain supplementary cementing materials (SCMs), such as fly ash or slag cement, and chemical admixtures (Figure 1-1).
