摘要

Types of concrete that permits water to penetrate through it because of its high void or porosity is known as pervious concrete. These studies look into the impact of size of aggregate (20mm and 10mm), w/c ratio (0.32 & 0.28), super plasticizers (auramix 400 & conplast sp 430) and different percentage of fibre (i.e 1% & 2%) on the behavior of pervious concrete and were described the resemblance with 4 criteria: Compressive strength, split tensile strength, flexural strength, and permeability test. The result indicates that there is moderate increase in strength with decrease in w/c ratio from 0.32 to 0.28 & moreover super plasticizer (conplast sp 430) gives good strength. Addition of fibre i.e 1% by weight of cement showed a significant role in increase in strength. However porosity was the most consider shrewd potency of porous concrete in calculating efficiency of porous concrete which was affected by addition of certain percentage of fibre. The result of this investigation provided useful information about effectiveness of w/c ratio, super plasticizer, fibre and compaction to achieve the optimal strength drain ability balance, adequate for the different urban uses.

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
