Durability aspects of concretes made with boron-activated high belite cement (HBC)
Boron-activated high belite cement could be a promising alternative to ordinary Portland cement to provide considerable energy savings and to reduce the environmental impacts of concrete production. However, this material has little practical use in industry without satisfactory durability, which is a fundamental feature of serviceable concrete structures subjected to working conditions. Experimental research was conducted to ascertain the durability of the concretes made with boron-stabilized high belite cement (HBC) over that of ordinary cement (OPC)-based concretes. Four concrete mixtures were designed with HBC and OPC at 0.35 and 0.55 w/c ratios. Apart from early and late compressive and tensile strengths, the durability of the concretes was tested for free and restrained shrinkage, water and chloride ion permeability, and accelerated corrosion resistance. Test results revealed that the concretes with HBC demonstrated outstanding durability performance than compared to OPC-concrete in many aspects owing to its high belite content leading to much less calcium hydroxide, thus providing a denser matrix and interface in the concrete.
