Abstract

This paper presents the properties of high-strength concrete containing a high volume of N-class natural pozzolan sourced from the Northern part of Vietnam. Based on the conducted studies' results showed that the mechanical properties of the natural pozzolan concrete were generally lower than those of control concrete. However, with effects combined of natural pozzolan and SR-5000F superplasticizer on the microstructure of concrete, mechanical properties of high-strength concrete increases with the amount of natural pozzolan from 10 to 20% by mass of cement, then descends. In addition, the maximum temperature of both conventional and High-strength concrete specimens significantly decreases with the increasing content of natural pozzolan. Furthermore, the relationship between compressive and flexural strength, modulus of elasticity and compressive strength of heavyweight concrete specimens are also determined in this investigation.
