Novel steaming-free air-adding brick formula and production technology thereof

Abstract

The invention relates to a novel steaming-free air-adding brick formula and a production technology thereof, which belong to the technical field of building material. The brick of every cubic meter comprises the following components by mass ratio: 400-500 kilograms of sand, 240-250 kilograms of ordinary silicon cement 425, 20-30 kilograms of quicklime, 600-650 grams of aluminium powder, wherein the proportion of air-entrainer and water reducer to cement is 1%, and 155-225 kilograms of hot water at 70-75 DEG C. A production technology comprises the following steps: dumping sand in a mixer; adding hot water when stirring can be carried out, adding water for stirring while adding the water reducer; adding water for stirring while adding the air-entrainer; adding cement for continuously stirring; adding quicklime for continuously stirring; and adding aluminium powder for continuously stirring; wherein the temperature of the stirred mortar is more than 35 DEG C. The invention improves the current steaming-free air-adding brick formula and the production technology, so that product with excellent performance can be produced, and the produced product is easily maintained, and the intensity is higher.

Description

Technical field: [0001] The invention relates to the technical field of building materials, in particular to a formula for a novel steam-free aerated block brick and its production process. Background technique: [0002] Bricks are small man-made blocks used in construction. They are divided into sintered bricks (mainly clay bricks) and non-sintered bricks (sand lime bricks, fly ash bricks, etc.), commonly known as bricks. Clay bricks are made of clay (including powders such as shale and coal gangue) as the main raw material, which is processed, shaped, dried and roasted by mud. [0003] The standard specification of ordinary bricks (solid clay bricks) is 240 mm × 115 mm × 53 mm (length × width × thickness). [0004] Porous clay bricks vary according to the situation of each area, and the thickness of the outer wall is generally 240 mm or 370 mm. According to the compressive strength, it is divided into 6 strength grades: MU30, MU25, MU20, MU15, MU10, and MU7.5. [0005] Clay bricks...
