Abstract

The invention discloses a full-hole-slag high-performance concrete and a preparation method thereof. The full-hole-slag high-performance concrete is prepared from the following raw materials by weight: 720-770 parts of ordinary Portland cement, 300-330 parts of fly ash, 2000-2200 parts of hole slag coarse aggregate, 1460-1760 parts of hole slag fine aggregate, 35-55 parts of a polycarboxylate superplasticizer and 320-370 parts of water, wherein the hole slag coarse aggregate is hole slag with a particle size of 5-25mm, and the particle size of the hole slag fine aggregate is 0-5mm, all the rawmaterials are sequentially mixed and stirred to prepare the full-hole-slag high-performance concrete. The hole slag is used as coarse aggregate and fine aggregate of the concrete, the prepared full-hole-slag high-performance concrete has excellent working performance and mechanical performance, consumption of natural gravel resources is reduced, the engineering construction efficiency is improved, and the engineering cost is reduced.

Description

technical field

[0001] The invention relates to the preparation of building materials, in particular to a full-hole slag high-performance concrete and a preparation method thereof. Background technique

[0002] Traditional concrete generally uses river sand as the fine aggregate, and pebbles or crushed stones as the coarse aggregate. Demand continues to increase. Over-exploitation of natural river sand will have a great negative impact on river bank stability, flood control safety, and ecological environment. Excessive extraction of gravel will destroy surface vegetation and cause a series of problems such as floods and droughts.

[0003] The rapid advancement of infrastructure requires the consumption of a large amount of concrete raw materials. Existing concrete consumes natural sand and gravel resources and is expensive. Contents of the invention

[0004] Purpose of the invention: The purpose of the invention is to provide a full-hole slag high-performance concrete and...
