Embodiment 1

[0015] The raw material formula of small sand bricks is: 60% river sand, 20% rock powder, 10% 425# cement, 10% slag powder, and an early-strength water reducer with 0.8% cement as a strengthening agent.

[0016] The above raw materials are prepared according to the following steps:

[0017] 1) Add water and stir with river sand, rock powder, 425# cement, slag powder and early-strength superplasticizer according to the above ratio.

[0018] 2) Send it into the brick making machine and press it into bricks, and the pressing pressure is 100T / m2;

[0019] 3) Health preservation, send the formed bricks into the greenhouse for health preservation, and ensure that they are not drenched in water within 5-8 hours, and then pour water every 4 hours, and drench thoroughly. The humidity in the greenhouse is 5-10 degrees, and the temperature The temperature is about 30 degrees, the ventilation is good, and the health preservation period is about 10 days.

Embodiment 2

[0021] The raw material formula of small sand bricks is: river sand 55%, rock powder 25%, 425# cement 8%, slag powder 12%, and early-strength water reducer with 1% cement content is added as a strengthening agent.

[0022] The above-mentioned raw materials are prepared according to the following steps:

[0023] 1) Add water and stir with river sand, rock powder, 425# cement, slag powder and early-strength superplasticizer according to the above ratio.

[0024] Following steps are with embodiment 1.

Embodiment 3

[0026] The raw material formula of small sand bricks is: 70% of river sand, 10% of rock powder, 15% of 425# cement, 5% of slag powder, and an early-strength superplasticizer with a cement content of 0.6% is added as a strengthening agent.

[0027] The above-mentioned raw materials are prepared according to the following steps:

[0028] 1) Add water and stir with river sand, rock powder, 425# cement, slag powder and early-strength superplasticizer according to the above ratio.

[0029] The following steps are the same as in Example 1.

Abstract

The invention discloses a small sand brick and a preparation method thereof. According to the formula, the small sand brick is prepared from the raw materials: 50-70% of river sand, 10-30% of rock powder, 5-15% of Portland cement, 5-15% of quenched blast furnace slag, and 0.6-1.2% of the cement amount of a reinforcing agent; and the raw materials are added with water to be uniformly stirred and pressed into the brick by a brick machine. Since the raw materials adopted are the river sand and industrial waste residue, soil is not taken and vegetation is not damaged, not sintering is performed inthe production process and a large amount of fuel is saved, no pollution is caused to the atmosphere, and various waste residue is further utilized in a large amount, so that the urban environment ispositively protected; and the production cycle is short, the cost is low, and the strength is high.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a small sand brick and a preparation method thereof. Background technique [0002] Existing sintered bricks (red bricks) need a large amount of coal in the production process, which not only wastes energy, but also seriously pollutes the environment. Due to the harmfulness of its pollution, relevant national policies have restricted the production of this kind of bricks, and Tichang produces unfired bricks. The production of non-fired bricks generally uses sand and cement as raw materials, but the proportion of the produced bricks is too large, which brings big problems to the construction industry. The purpose of the present invention is to provide a kind of small sand brick that can save soil resources in production process, save energy, protect environment, cost is low, brick body compressive strength, high flexural strength and reduce brick specific gravity and pr...
