Abstract

The invention discloses high strength concrete and its preparation method, and relates to the technical field of building materials. 1 m<3> of the high strength concrete comprises the following ingredients: 200-300 kg of ordinary Portland cement, 40-50 kg of mineral powder, 15-30 kg of rubber particles, 500-800 kg of fine aggregate, 600-900 kg of coarse aggregate, 20-60 kg of a concrete composite additive, 50-100 kg of polypropylene fiber, 100-200 kg of water, 45-90 kg of phosphorous slag powder, 2-3 kg of a corrosion inhibitor, 5-10 kg of a water reducing agent, and 10-20 kg of a reinforcing agent. According to the prepared concrete product, compressive strength is remarkably raised, cracks are minimized, and life of concrete structures is prolonged. In addition, the preparation method is simple, and production efficiency is high.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a high-strength concrete and a preparation method thereof. Background technique [0002] Concrete is everywhere in our lives. Whether it is roads, bridges, buildings, ports, docks, dams, airports, or Antarctic research stations and ocean drilling platforms, people can touch it all the time, and scientists are still studying the use of cement concrete materials for the outer layer space. [0003] At present, in many underground projects, especially large-volume concrete projects, concrete cracks are more common. The main reason is that the compressive strength of concrete is too low. In order to prevent concrete from cracking, it is generally used to add expansion agents, but adding expansion agents increases the cost of concrete. , and it needs to be supplemented by manual addition, which increases labor intensity and environmental pollution. If an automated process ...
