A study the mechanical properties of concrete mixed microorganisms. By means of low pressure steam curing

Abstract

This research aims to study the mechanical properties of the concrete mix microorganisms. By curing steam There are variables to test the amount of microbial powder instead of cement. The ratio of 0, 1, 2, 3, 4 and 5 by weight of material. There are ways of curing concrete curing normal and steam curing. Test for compressive strength at age 3 days, 7 days, 14 days and 28 days. From the test results Using the example cylindrical Diameter 10 cm high 20 cm found the strength to rise. By The incubation period in a concrete way, when the second test concrete curing normal and steam curing compared. It is seen that the compressive strength of concrete by means of steam curing the compressive strength greater than normal incubation. Following a period of curing concrete. The average increase by approximately 28-30 percent of compression by means of conventional breeding. When using powdered bacteria effective to replace cement in the ratio of 0, 1, 2, 3, 4 and 5, respectively, found that the concrete has developed a compressive strength greater, respectively, in proportion to replace the two series. How curing concrete.
