Strength and Durability of High Performance Concrete Doped New Low Clinker Cementing Material

Abstract

A new low clinker cementing material applying to different concrete strength is developed in this paper. The experiential results show that standard consistency water consumption of the new material is less than the ordinary material; and the particle size is better than the ordinary material. And the cracking performance of the concrete made by the new material is far better than the performance of the concrete made by the ordinary material. Furthermore, the shrinkage of the concrete made by new material is less; and the resistance ability to carbonation is higher. Especially, our proposed new material could make the gel body dense and become six components of concrete into four, which simplifies the production process of concrete mixing station. At the same time, the prepared concrete made by the new material has better construction performance, volume stability and high durability. Unfortunately, the initial and final setting time of the new material are slightly longer. However, the initial and final setting time are still able to meet the national requirements. And most of all the new material meets the requirements of green high performance concrete.
