Problems solved by technology

The preparation of concrete in the prior art is simply to mix polycarboxylate and other water reducing agents with cement, mineral powder, and fly ash according to the designed ratio, and the pumping effect and strength increase of the obtained concrete are not very ideal. And the total gel material consumption is high, it is difficult to save cost
This kind of concrete has poor workability and short setting time, which is not conducive to long-distance transportation, which makes the pumping performance of high-rise structures unsatisfactory.

Embodiment Construction

[0028] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0029] Such as figure 1 Shown, a preferred embodiment of the present invention provides a kind of preparation method of concrete, comprising:

[0030] 1) Preparation and weighing of raw materials:

[0031] The raw materials include cement, mineral powder, fly ash, crushed stone, fine stone, debris, fine sand, water, polycarboxylate water reducer and glue reducer;

[0032] The crushed stones, fine stones, chips and fine sand are transported to the respective warehouses in the aggregate bin through the belt conveyor, and each warehouse is equipped with electronic weighing scales, and the required crushed stones are weighed through the corresponding electronic weighing scales , fine stone, debris and fine sand, and then transport the weighed gravel, fine stone, debris and fine sand to the storage bin;

[0033] The mineral powder is conveyed to the miner...

Abstract

The invention discloses concrete. The concrete comprises the following materials in percentages by mass: 12.3% of cement, 3.2% of mineral powder, 2.1% of fly ash, 37.7% of crushed stones, 5.7% of finestone, 18.2% of fragments, 13.2% of fine sand, 7.2% of water, 0.3% of a polycarboxylate superplasticizer and 0.1% of a glue reducing agent. The invention further provides a preparation method of theconcrete. The concrete has the advantages of low preparation cost, good peaceability and high growth of compressive strength.

Description

technical field [0001] The invention relates to the field of building materials, in particular to concrete and a preparation method thereof. Background technique [0002] Concrete is the most widely used building material in modern times. It has the advantages of abundant raw materials, low price, simple process, high strength and durability. The preparation of concrete in the prior art is simply to mix polycarboxylate and other water reducing agents with cement, mineral powder, and fly ash according to the designed ratio, and the pumping effect and strength increase of the obtained concrete are not very ideal. And the total gel material consumption is higher, it is difficult to save cost. This kind of concrete has poor workability and short setting time, which is not conducive to long-distance transportation, which makes the pumping performance of high-rise structures unsatisfactory. Contents of the invention [0003] The object of the present invention is to provide a ...
