Netesa N. 3. Scientific of the bases high of efficiency use of cement in the concrete

The object - concrete with low outlay of the cement for wich need provide improve of the structure when outly a cement a minimum; the aims - creation of scientific bases of increase effectivness uses of the cement in a concrete purposeful improvement of the structure; the methods - mathematicals of the models, a calculation experiment, a statistical of the analyssis; the new - first determine of the reasons low effectiveness uses of the cement in the concrete of low strength and fix of the principl conception rise effectivness on the base a cement in the concrete intention improvement of the structure providt rational grainion composition of the concret mixture; the results - reseive of the concrete with best structure and need property with rise in 2 time the coefficient use of the cement, elaborate the tecnecal arranges for concrete with the fillers; all this thesis has by the enterprises of a building structure; the field is construction
