摘要

In order to prepare C30 permeable concrete, the effects of water-cement ratio, mixing method, forming process and curing method on the porosity, permeability coefficient and compressive strength of permeable concrete were investigated. The permeable concrete was applied by SEM and XRD. The microstructure and chemical composition of the cemented layer were analyzed. The results show that when the amount of other ingredients is the same, increasing the amount of cement can effectively improve the strength; the mixing method of cement stone can enhance the bond between the aggregate and the cemented material; with the increase of vibration time, the compressive strength of the permeable concrete Gradually increase, but the vibration time is too long, there will be a phenomenon of sedimentation; in the early stage of conservation, the water conservation can make the hydration reaction fully; 28d permeable concrete sample hydration reaction is more thorough, generating a large amount of CSH gel.

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
