Mechanical Properties of Porous Concrete by Effective Microorganisms (EM) Mixed

Abstract

This research studies the development of the mechanical properties of porous concrete using effective microorganisms (EM), a combination intended. To study the mechanical properties of porous concrete using effective microorganisms (EM) and the mixture is a mixture of Effective Microorganisms (EM) is right in doing so including the development of properties of porous concrete, the compressive strength and the compressive strength of high performance by using microorganisms (EM) of porous concrete. By making a comparison between the normal water curing and curing at 100% water efficient microbial Effective Microorganisms, EM was 90%: 10% and 80%: 20% at ages 3,7,14 and 28 days of incubation to study the change of resistance of the concrete compressive strength ratio of different porosity. Research to improve the mechanical properties of porous concrete using effective microorganisms (EM) is a compound found porous concrete. After incubation at 28 days of age with the development of resistance, compressive strength increased. Can be cured with a ratio of water to microbial efficiency Effective Microorganisms, EM 90%: 10% resistance strength increased as 198.333 ksc., And incubated with water microbial efficiency Effective Microorganisms, EM 80%: 20% will have lower average compressive resistance equals 186.667 ksc.
