CONCRETE MEMBERS WITH EXCELLENT COMPRESSION RESISTANCE AND FROZEN ENERGY, COMPOSITION, AND COMPOSITION FOR PREPARING CONCRETE ELEMENTS HAVING REMARKABLE COMPRESSIVE RESISTANCE AND FRACTURE ENERGY, AND ELEMENTS OBTAINED THEREBY

摘要

SUMMARY OF THE INVENTION The present invention relates to a pressure sensitive adhesive composition having a compressive strength of at least 400 MPa and a compressive strength²The present invention relates to the production of concrete having crushing energy. After mixing and setting the mixture substantially containing cement, fine sand, amorphous silica, ground quartz, steel surface, fluidizing agent and water in specific proportions, the concrete is heated at a temperature of at least 250C. The drawings are electron micrographs showing the microstructure of the concrete according to the present invention. The present invention is particularly used in the manufacture of concrete portions of anchoring heads for compressive stress cables, for example, instead of steel.
