 · Concrete is a construction material that consists of cement (commonly Portland cement) aggregate (generally gravel and sand) water and admixtures.. Concrete solidifies and hardens after mixing and placement due to a chemical process known as water reacts with the cement which bonds the other components together eventually creating a stonelike material.

Feasibility study of "green" insulation materials

This study investigates the effect of carbon nanotube (CNT) dispersion on the mechanical properties and microstructures of ultralight foamed concrete. A type of uniform and stable CNT dispersion solution is obtained by adding nanoCe(SO4)2. Results show that CNT dispersion increases the compressive and breaking strengths of foamed concrete. CNTs play a nuclear role in the crystallization of C
