A semi-rigid concrete and its preparation process

The present invention discloses a semi-rigid concrete and its preparation process, the semi-rigid concrete as fine aggregate will replace the ordinary concrete material obtained by mixing a portion of the flexible material is concrete, the fine aggregate is replaced with the replacement with the mass the same mass of said flexible material; flexible material composition by mass of: 30% to 40% powder, 30% to 40% rubber, the polypropylene fiber of 0.5% to 1.5%, 3% to 8% ash , mineral admixture of 20% ~ 28%; required zinc stearate powder and colloidal rubber particles and rubber powder surface is removed by a strong base solution; preparation process comprising the steps of: a, preparation of flexible material and scale level with a combination thereof; two, semi-rigid concrete preparation. Step preparation process of the present invention is simple, easy to operate and low investment cost, use of effective, to make up for the presence of a small modification of the conventional ordinary concrete, brittle, tensile strength and low defect.
