Abstract

The invention discloses a novel concrete. Raw materials of the concrete comprise the following components: Portland cement, coarse sand, medium coarse sand, detritus, water, steel slag, siliceous irontailing powder, gypsum, high-calcium ash, silicon powder, glazed hollow beads, a polycarboxylate superplasticizer, sodium molybdate, sodium nitrite, tin chloride, natural zeolite micropowder, synthetic fibers, an air entraining agent, urea and triethanolamine. The novel concrete disclosed by the invention is reasonable in component and synergic in effect, has high durability such as high strength, high freezing resistance, high impermeability and good corrosion resistance and also has advantages such as noise insulation.

Description

technical field [0001] The invention relates to the technical field of concrete, in particular to a novel concrete. Background technique [0002] Concrete is the most used building material today, and high-performance concrete represents the development direction of concrete technology. The wall column is an important part of the construction project. It bears the force of the entire construction project. As the main structure of the entire construction project, the quality requirements are very high. Concrete is one of the main construction materials in the wall construction process. The quality of the concrete material has a serious impact on the construction quality of the wall column, and affects the service life and use function of the project. At present, the impermeability and corrosion resistance of concrete still need to be improved. Contents of the invention [0003] Based on the technical problems in the background technology, the present invention proposes a ...
