LIGHT-WEIGHT AERATED CONCRETE MIX METHOD USING THE SPECIAL COMPOSITION WITH EMHANCEMENT OF CRACK CONTROL AND FLEXURAL PERFORMANCE

摘要

Disclosed are light-weight aerated concrete composition using admixtures and fibers which are optimally composed to improve a crack control and flexural strength performance during a manufacturing process of light-weight aerated concrete, and a manufacturing method of the light-weight aerated concrete using the same. According to the present invention, the light-weight aerated concrete composition includes: a binding material including 40-80 wt% of cement and 20-60 wt% of admixtures; reinforced fibers having 0.3-1.2 kg per 1 m^3 of the binding material to improve a crack control and flexural strength performance of aerated concrete; 20-40 wt% of water, which serves as mixing water, with respect to the binding material; and 50-70% of foam on a basis of volume after curing the aerated concrete.
