Correct Answer: Joseph Aspdin

Solution : The correct answer Joseph Aspdin

Joseph Aspdin was born in England in 1779. He is credited for the invention of cement and got the patent for portland cement. He was an English businessman, inventor and stonemason. While experimenting he found that when clay and limestone are heated at very high temperature then after cooling and grinding it cement is produced. When it is mixed with water it forms a very strong and stable substance. This property of cement makes it best to be used as binding agent with concrete for strong architectures.
