Study on Performance of High Performance Concrete Prepared from Kenya Natural Volcanic Ash in Kenya |
| |
| Abstract: | A poly carboxylic acid water reducing agent with optimal adaptability is selected by comparison based on adaptability study on four kinds of poly carboxylic acid water reducing agent, and all properties of the high performance concrete prepared from two kinds of Kenya natural volcanic ash. The results show results that the high performance concrete with good constructability, mechanical property and durability can be prepared by the poly carboxylic acid water reducing agent(KL-3) and # 2 ash. |
