Hussin, Manal and Zhuge, Yan and Bullen, Frank and Lokuge, Weena (2011) Laboratory evaluation of the stress-strain relationship of permeable concrete. In: CEABM 2011: 1st International Conference on Civil Engineering, Architecture and Building Materials , 18-20 Jun 2011, Haikou, China.

Abstract

The authors conducted research aimed at developing a new type of permeable concrete material with enhanced structural strength. This paper presents and discusses the results of their investigation on the unaxial compressive stress-strain relationship of porous concrete made with two different mix designs with constant water to cement ratio. The concrete mixes were designed with a target compressive strength between 15-25 MPa and target porosity between 10-15% to study the effect of pore sizes on the stress-strain curve. The average pore space was increased by increasing the relative amount of large aggregate. The reduction in the relative amount of fine aggregate increased the average pore space and resulted in a reduction in mix stiffness and a marginal increase in ultimate strength.
