Description
The present invention relates to be used for the cement of concrete and goods thereof, especially for having the concrete that high-durability can require and the cement of goods thereof.Belong to building material field.
Preparation of high efficient concrete (High Performance Concrete-HPC) is a kind of new concrete of country's research and development recent years such as France, the U.S., Japan, Canada, and its more traditional concrete on the proportioning mentality of designing has had a new breakthrough.Compare with traditional concrete; preparation of high efficient concrete has characteristics such as high application property (satisfying pumping or little requirement of shaking), high strength (intensity was not less than 50MPa in 28 days), low drying shrinkage, high permeability resistant, high-durability, is applicable to the concrete works that Highrise buildings, bridge, high tower, nuclear reactor protection shell and antiknock engineering etc. have increased durability to require.
Announced June 29 at French Patent FR2640962A1(90) in method with starting material such as silicate cement, liquid agent, defoamer, silicon ash, quartz sand powder, steel fiber, normal sands, cobble preparation preparation of high efficient concrete is proposed, this concrete can be used in the military antiknock engineering, and mark is supported following 28 days ultimate compression strength of condition and reached 70MPa.Countries such as Japan, the U.S. then adopt the method for the high-effect water reducer of low water-cement ratio (W/C=0.25～0.35) while admixture, an amount of active addition, swelling agent or thickening material to prepare preparation of high efficient concrete at the construction field (site), used cement is silicate cement, and high-effect water reducer mostly is liquid.The above-mentioned method for preparing preparation of high efficient concrete requires construction department to purchase multiple starting material and admixture simultaneously, at the construction field (site) or concrete mixing plant repeatedly measure computing, complex manufacturing technology, the production cost height, simultaneously construction technical staff is had relatively high expectations, have carelessness just may cause accident resulting from poor quality of projects slightly.
The purpose of this invention is to provide a kind of cement special, can be with this cement special at the construction field (site) directly by general concrete formulating method, promptly water, common sand, stone and cement are mixed with preparation of high efficient concrete.
