Abstract:Based on thorough analysis on the physical, mechanical and chemical characteristics of cement, water, sand, gravel, fly ash and steel bars, this paper deemed that too much cement paste induced the non-structural cracks of commercial house floors. Increasing the amount of gravel, optimizing the grading of aggregate and reducing the amount of cement paste were the fundamental ways which eliminated this kind cracks. The advantages and disadvantages of "throwing aggregate method" and "un-pumping commercial concrete" and how to control non-structural cracks of commercial house floors in construction methods were discussed in this paper.
Keywords:house  crack  cement  floor
