The water reacts with the cement, which bonds the other components together, eventually creating a strong stone-like material.(a) True(b) FalseI have been asked this question in a job interview.My doubt is from Analysis of Rates of Cement Concrete topic in chapter Analysis of Rates of Civil Engineering Drawing
Answer» RIGHT option is (a) True The best I can explain: Concrete is USED more than any other man-made material in the world. As of 2006, about 7.5 billion cubic meters of concrete are made each year—more than one cubic meter for every person on Earth. The ingredients are mixed together into a paste, a BIT like making dough for bread. The concrete is then poured into a frame. After a few hours it sets HARD.
