Problems solved by technology

[0004] However, this technical solution uses mountain crushed stones mined from limestone mountains to prepare concrete. During the mining process of mountain rocks, mountain blasting and crushing are generally required to obtain mountain crushed stones. During the crushing process, a large number of edges and corners will be produced on the surface of the crushed stones , forming a matte gravel surface that adversely affects the fluidity of concrete products

Embodiment 1

[0039] Embodiment 1: a kind of mountain crushed stone material concrete, comprises the steps:

[0040]S1 Pulping: Use screens with apertures of 25mm, 20mm, 5mm, and 0.5mm to sieve mountain crushed stones, weigh 2.9Kg of crushed stones with a particle size of 20mm-25mm, and weigh 62.4Kg of crushed stones with a particle size of 5mm- 20mm crushed stone particles, 55.1Kg crushed stone particles with a particle diameter of 0.5mm-5mm, and 24.6Kg crushed stone particles with a particle diameter not greater than 0.5mm, totaling 145Kg, and mix well. Sieve HY-type molecular sieve with a sieve with a pore size of 5mm, sieve diatomite with a sieve with a pore size of 5mm, add 0.4Kg of HY-type molecular sieve with a particle size not greater than 5mm and 6Kg of HY-type molecular sieve with a particle size not greater than 5mm of diatomite, mix evenly, then add 25Kg of water, stir evenly to obtain a wet material, transfer the wet material to a ball mill, and the ball mill contains 70Kg of ...

Embodiment 2

[0044] The difference between embodiment 2 and embodiment 1 is that attapulgite is not added in embodiment 2, and the others are consistent with embodiment 1.

Embodiment 3

[0046] The difference between embodiment 3 and embodiment 1 is that embodiment 3 is not processed by ball milling. In embodiment 3, the mountain crushed stone material, HY type molecular sieve and diatomaceous earth are mixed evenly, and then 25Kg of water is added and stirred evenly to obtain a slurry Material, others are consistent with embodiment 1.

Abstract

The invention discloses mountain gravel concrete and a preparation method thereof, belonging to the technical field of concrete preparation. The mountain gravel concrete is mainly prepared from the following concrete raw materials in parts by weight: 1350 to 1550 parts of mountain gravel, 400 to 460 parts of cement, 220 to 280 parts of water, 2 to 5 parts of a molecular sieve and 40 to 80 parts ofdiatomite, wherein the concrete raw material further comprises an admixture, and the admixture comprises the following admixture raw materials in parts by weight: 8-12 parts of a water reducing agent, 5-10 parts of sodium hydroxyethyl sulfonate and 0.5-3 parts of a defoaming agent. The mountain gravel concrete has the advantage of good fluidity. The preparation method of the mountain gravel concrete comprises the following steps: pulping, admixture preparation, concrete preparation and the like. The preparation method of the mountain gravel concrete has the advantage that product flowabilityis conveniently improved.

Description

technical field [0001] The invention relates to the technical field of building material preparation, in particular to mountain crushed stone concrete and a preparation method thereof. Background technique [0002] Concrete is a material made of cementitious materials, gravel, sand and water in a certain proportion. Concrete has the characteristics of high strength, excellent durability and simple production process. It is widely used in high-rise buildings, road and bridge construction and other fields. application. In the process of concrete production, a large amount of concrete stones such as stones and sand are used. In the actual production process, there are mainly two types of concrete stones: one is pebble stones mined from rivers, and the other is mined from mountain rocks. Mountain gravel. Because pebbles are easy to mine and the cost is low, more pebbles were used in the previous construction process. However, the mining of pebbles in the river has brought cer...
