摘要

Temperature affects the way concrete gains strength. High temperatures tend to accelerate early age strengths but decrease later strengths, while low temperatures retard early age strengths and increase later strengths. It is well known that freezing concrete at an early age can result in permanent damage. What is not well known or appreciated is that concrete can benefit from the cold. Cold weather often results in concrete of superior strength, compared to concrete cast during warm weather, and if fresh concrete is frozen at an early age, it can recover full potential strength when thawed. The problems as well as the opportunities of low temperature concreting are discussed.

7. Mechanical properties of various concrete after high temperature exposure Mechanical property of various types of concrete after high temperature exposure is investigated. Considering compressive strength requirement for a vertical element in high rise building, concrete specimens with various design strengths of 35, 80, 100, and 150 MPa were tested. Particularly, the influence of incorporated steel fiber on fire resistance is of interest in this study. Experimental results show that the fire resistance depends on the design strength and steel fiber content. Normal strength concrete (NSC) of a design strength of 35 MPa or high performance concrete (HPC) of 80-100 MPa does not spall when exposed to 100-400 °C of temperature. However, an explosive spalling occurs at 300 °C when the HPCs contain 1 vol. of steel fiber. Ultra-high performance concrete (UHPC) of a design strength of 150 MPa and 1.5 vol. of steel fiber also shows dramatic spalling at 300 °C. The experimental results found in this study can contribute to a better understanding of the behaviors of HPC and UHPC under fire and the role of steel fiber on the fire resistance. [O] . 2017
