Abstract
The invention discloses high-density rubber high-performance concrete and a preparation method thereof. The concrete comprises the following raw materials in parts by weight: 390-450 parts of cement; 50 to 100 parts of mineral powder; 20 to 60 parts of high-density rubber particles; 500 to 750 parts of sand; 1000 to 1100 parts of broken stone; 4 to 5 parts of a water reducing agent; and 145 to 155 parts of mixing water. The preparation method comprises the following steps: respectively weighing the high-density rubber particles, the cement, the mineral powder, the sand, the broken stones, the water reducing agent and the mixing water according to a set mixing ratio, putting the materials into a concrete mixer, and uniformly mixing to obtain the high-density rubber concrete. The high-density cement-based powder material is adhered to the surfaces of the rubber particles, so that the density of the rubber particles is effectively improved, the density of the rubber particles is equivalent to that of aggregate, distribution of the rubber particles in concrete is effectively improved, the rubber particles are effectively adhered to a concrete matrix, and the performance of the high-density rubber high-performance concrete is guaranteed.
Description
technical field [0001] The application belongs to the technical field of rubber concrete, and in particular relates to a high-density rubber high-performance concrete and a preparation method thereof. Background technique [0002] As one of the most widely used building materials in construction, concrete is plagued by problems such as high brittleness, insufficient toughness, and shortage of raw material resources. At the same time, with the continuous increase of my country's automobile production, the amount of discarded tires is increasing day by day, and a large number of discarded rubber tires cannot be effectively processed, which has caused a serious burden and adverse effects on the environment of our country. Therefore, the use of rubber particles processed from waste tires as concrete aggregates can solve the problem of shortage of concrete raw materials and the problem of rubber waste disposal, turning waste into treasure, and is conducive to environmental protec...
