Problems solved by technology

However, the existing crushing methods are difficult to achieve fine crushing of construction waste. Usually, multiple crushing processes are required to obtain small crushed stones, which takes a long time to process and low work efficiency; and requires the use of multiple different processing equipment. The cost of equipment investment is high and energy consumption is high; and the qualified rate of the final crushed stone is low, which is difficult to meet the needs of processing high-quality concrete; and the strength of concrete prepared by traditional methods is low, which affects the firmness of buildings

Abstract

The invention discloses a processing technology for preparing high-strength concrete. The processing technology comprises the following steps: (1) raw material preparation: taking cement, sand, water,a water reducing agent, phenolic fiber and montmorillonite, wherein the sand is obtained by crushing construction waste by a crushing apparatus; (2) dry mixing: putting the cement, the sand, the water reducing agent, the phenolic fiber and the montmorillonite into a material mixing machine for dry material pre-mixing to obtain a mixture A after uniform mixing; and (3) wet mixing: putting the mixture A into a stirrer, adding water and a fine aggregate into the stirrer, and then performing uniform stirring to obtain the slurry-like concrete. According to the processing technology, the dry mixing operation is first performed before the wet mixing, so that a mixing uniformity degree of the dry powder materials is relatively high during mixing, and the processing technology ensures that various materials are all mixed together.

Description

technical field [0001] The invention belongs to the technical field of construction, and in particular relates to a processing technology for preparing high-strength concrete. Background technique [0002] The preparation of concrete requires a large amount of sand and gravel. Due to the shortage of sand and gravel resources, people began to use crushed construction waste to replace sand and gravel to meet the demand for sand and gravel in construction projects. However, the existing crushing methods are difficult to achieve fine crushing of construction waste. Usually, multiple crushing processes are required to obtain small crushed stones, which takes a long time to process and low work efficiency; and requires the use of multiple different processing equipment. The investment cost of equipment is high, and the energy consumption is large; and the qualified rate of the final crushed stone is low, which is difficult to meet the needs of processing high-quality concrete; and...
