This article surveys the historical development of cement, its manufacture from raw materials, its composition and properties, and the testing of those properties.

Concrete is an aggregate (like sand, crushed rock or the like), water and (usually Portland) cement plus a little bit of a couple or three other other chemicals to adjust the consistency of the final product. Basically we just use sand, water and cement to mix up this familiar construction material ...

Green cement is a cementitious material that meets or exceeds the functional performance capabilities of ordinary Portland cement by incorporating and optimizing recycled materials, thereby reducing consumption of natural raw materials, water, and energy, resulting in a more sustainable construction material.

Concrete is a friend of the environment in all stages of its life span, from raw material production to demolition, making it a natural choice for sustainable home construction.

The cement raw material blending process is an important link because the blending process will affect the cement clinker quality and critical cement craft parameters, thus the blending process finally affects the cement quality.

Refractory cements and raw materials differ in terms of cement properties and material features. Cement properties include maximum use temperature, thermal conductivity, modulus of rupture (MOR) or flexural strength, compressive strength, particle or aggregate size, density, and shrinkage. Material features indicate whether refractory cements ...
