Influence of High Temperature on Concrete Produced from Portland Cement with Boron Additives

Abstract

The boron compounds have been widely used as additives in the production of cement and concrete to enhance their engineering properties. In this study, three series of concrete specimens were produced using B2O3 additive materials, boron modified active belite cement and Portland cement. After 28 days of curing period the specimens were exposed to temperatures of 250, 500 and 750• C. Mass loss and compressive strength were determined and recorded after the specimens were cooled to room temperature. It was concluded that the effect of the boron becomes more apparent at high temperatures.

High Temperature Performance of Self-Compacting Concrete Containing Boron Active Belite Cement

“…Davraz et all. [49] stated that the compressive strength of concrete with BABC decreased in the temperature range of 500°C. Hence, it suddenly decreased at the 750°C.…”
