Study on the Properties of High Strength Concrete using High Belite Cement

Abstract

In this paper, the strengths under different curing conditions, heat evolution as well as resistance to sulphate have been discussed for High Belite Cement (HBC) in comparison with Ordinary Portland cement (OPC). In addition, R&D of high-performance concrete prepared by HBC as the main component of cementitious material with strength grades C50~C80 (equivalent to minimum requirement for 28-day compressive strength 50MPa~80MPa) was conducted. And the workability, physical mechanical properties, durability of HBC concrete have been discussed as compared to OPC concrete. The research results indicate that HBC possesses higher late strength after 28-day age though its early strength is relatively lower, lower hydration heat evolution and excellent resistance to sulphate. Moreover, HBC concrete exhibits excellent workability, physical mechanical properties and durability.

Recent Progress in Green Cement Technology Utilizing Low-Carbon Emission Fuels and Raw Materials: A Review

“…It has been reported that high belite cement not only lowers the heat evolution but also shows excellent workability, higher mechanical properties and durability. It also exhibited better sulfate and chloride resistance, lower drying shrinkage, and delayed strength gain but higher ultimate strength at later age compared to traditional OPC [86][87][88].…”

The influence of heavy metals on the polymorphs of dicalcium silicate in the belite-rich clinkers produced from electroplating sludge

“…In terms of engineering properties, belite-rich cements also have the advantages of low hydration heat, high flowability, good frost resistance, and excellent structural durability [10][11][12]. However, the hydraulic activity of belite-rich cements requires further consideration.…”

Alternative cement clinkers

“…RBPCs typically attain similar 28-day strengths to OPCs, and gain additional strength more rapidly than OPCs at later ages. [9] The performance of cements is generally compared in standard tests at a fixed temperature (20°C in Chinese and European standards). But in real applications the concrete temperature can vary over a wide range.…”
