Abstract

In vitro evaluation of additives allowed for high strength concrete (HSC) and foam concrete

Highlights

  • In today’s advanced world and with respect to advances in various fields, concrete industry has undergone major improvements including production of foam concrete which reduces the dead load of a concrete structure, mitigates earthquake-induced force to the structure and leads to lower debris weight after structure collapse [1]-[3]

  • This study aims to investigate the effect of using Micro Silica and plasticizer on strength of high strength concrete (HSC)

  • When the first sample faced failure; that is, mix design of the first sample could not reach the compressive strength and since the created concrete of this sample was dry and far lower than the required amount in terms of degree of workability, it was concluded that water/cement ratio should

Summary

Introduction

In today’s advanced world and with respect to advances in various fields, concrete industry has undergone major improvements including production of foam concrete which reduces the dead load of a concrete structure, mitigates earthquake-induced force to the structure and leads to lower debris weight after structure collapse [1]-[3]. Jiang et al [7] conducted a study on high-porosity foamed concretes made by ordinary Portland cement In their study, they examined all the effective parameters in such concretes and determined optimum value of each parameter. Guo et al [8], performed a theoretical and experimental study on non-linear, mechanical response of foamed concrete under non-axial compressive load over a wide range of temperatures and strain rates. They concluded that non-linear deformation behavior of foamed concrete undergoes various changes relative to changes in density and temperature
