What are the disadvantages of concrete
Disadvantages of ConcreteCompared to other binding materials, the tensile strength of concrete is relatively low.Concrete is less ductile.The weight of compared is high compared to its strength.Concrete may contains soluble salts. Soluble salts cause efflorescence.
Who invented concrete
Joseph AspdinIn 1824 Joseph Aspdin invented Portland cement by burning finely ground chalk and clay until the carbon dioxide was removed. Aspdin named the cement after the high-quality building stones quarried in Portland, England. In the 19th Century concrete was used mainly for industrial buildings.
