Further, described cement is P.O42.5 cement.
After having adopted technique scheme, the present invention has following beneficial effect:
1, the present invention can improve concrete workability: improved concrete agglutinating value(of coal) after adding BTC functional type admixture, the parcel of sand and rubble improves, concrete bleeding and segregability have been reduced, concrete flowability obviously improves, be convenient to pumping, and resistance is little during pumping, prolongs the work-ing life of pump line.
2, the present invention has also improved other performances of concrete simultaneously: after adding BTC functional type admixture, owing to effectively promoted the slurry volume, increased hydrated product, concrete homogeneity, water-retentivity, tensile property etc. are significantly improved, and effectively controlled bleeding, distress in concrete greatly reduces.Concrete self-compacting degree improves, and anti-permeability performance improves, and performances such as later stage freeze-thaw-, anti-carbonization are improved naturally, and the weather resistance of concrete has also improved.
3, the present invention has saved the glue material use quantity greatly, reduced production cost, the present invention is by repeatedly selecting to add BTC functional type admixture after the experiment, BTC functional type admixture is by the complexing chemical action, make cement based finely-powdered minerals material disperse cohesion again, improve concrete mortar and enrich degree, improve concrete cohesiveness; By shielding effect, suppress absorption and the swelling capacity of clay, improve the consistency of the complicated starting material of concrete and water reducer; By slackening water molecules polarity, eliminate the concrete bulla, increase microvesicle quantity, guaranteed concrete intensity and weather resistance effectively; By the lattice distortion effect, hydration reaction is accelerated, and reduces hydrated product crystal mineral quantity, improves jel product quantity, makes the reaction of secondary rubble more abundant, has greatly improved concrete grout-bone interface adhesive structure character.In a word, by the complex combination of multiple different properties functional materials, allow modern concrete can be more reliable with less gelling material production intensity, the concrete of more excellent performance, realize the tap/dip deep into of the low carbon technique of concrete and environmental protection aspect.
