Embodiment 1

[0016] Embodiment 1: A chemically foamed concrete self-insulating block, characterized in that: the ratio of raw materials contains 250kg of ordinary Portland cement based on 1m3 slurry; the mass ratio of other raw materials to ordinary Portland cement is as follows: iron, aluminum Salt cement 12.5kg, fly ash or river sand or pumice 50kg, Yuanming powder 1.25kg, hydrogen peroxide 10kg, water reducing agent 0.25kg, water 75kg, rubber powder 0.1kg, calcium stearate or lead stearate or hard Barium fatty acid 0.2kg, lithium carbonate 0.125kg.

[0017] Its specific process steps are as follows:

[0018] Step 1), batching: prepare materials according to the above proportions, store cement and fly ash or river sand or pumice transported by bulk trucks in cement tanks, and use electronic scales to weigh the above-mentioned raw materials through computer control to accurately and automatically measure batching;

[0019] Step 2), automatic mixing and stirring: use a high-speed mixer to...

Abstract

The invention relates to a chemically-foaming foam concrete self-heat-preservation building block and a production process thereof. The building block, on the basis of 1 m<3> of a slurry material, comprises 250-350 kg of ordinary Portland cement and other raw materials, on the basis of the mass of the ordinary Portland cement, 5-10% of iron aluminate cement, 10-20% of fly ash, river sand or float stones, 0.1-0.5% of anhydrous sodium sulphate, 2-4% of hydrogen peroxide, 0.2-0.4% of rubber powder, 0.1-0.3% of a water reducer, 20-30% of water, 0.4-0.8% of calcium stearate, lead stearate or barium stearate and 0.01-0.05% of lithium carbonate. The building block is simple in construction and good in heat preservation, reaches A grade in fireproofing, has same service life of buildings, is low in cost and greatly reduces delivery time.

Description

technical field [0001] The invention relates to a chemically foamed foam concrete self-insulation block used on the exterior wall of a building [0002] And its manufacturing process can solve the long-standing problem of a single self-insulating wall without an external wall, so that the construction of the wall is fast, the process is simple, the cost is reduced, and the external thermal insulation wall that really has the same life as the building. Background technique [0003] In recent years, my country's urban and rural construction has developed extremely rapidly. The construction area of ​​houses built every year is 400-600 million square meters in cities and towns, and 800-900 million square meters in rural areas. my country's cities and towns are accelerating, and the national urban construction area will reach 4-5 billion square meters during the "Twelfth Five-Year Plan" period. Among them, only 150 million square meters can meet the building energy-saving design ...
