Embodiment Construction

[0036] A sand air-entrained concrete anti-seepage block, each component includes the following formula in weight percentage:

[0037] Ground Quartz Sand 46%

[0038] Circulating Mortar 18%

[0039] Cement 21.52%

[0040] Lime 11%

[0041] Gypsum 3%

[0042] Aluminum powder 0.08%

[0043] Hydrophobic water repellent 0.4%.

[0044] The preparation method is as follows: according to the formula, each component is mixed and batched, stirred, statically stopped (including gas generation and hydration process, about 2.5 to 3.5 hours), cutting (including mold turning, six-sided cutting process, specifically, after cutting When using steel wire rope and cutter to cut six sides of the embryo body, the notch and shape of the product can be formed at the same time, so that the shape and size are more accurate, and the surface of the product will not produce oil stains), at a high temperature of 180-200 °C, a high pressure of 10-12 Curing under standard atmospheric pressure for 10 t...

Abstract

The invention relates to a sand-air impervious concrete masonry block adopting thin quartz sand, cement, lime and gypsum as main base materials and adopting aluminum powder as foaming agent; wherein, the sand-air impervious concrete block comprises a hydrophobic waterproof agent which occupies 0.02 to 0.40 percent of the total amount according to the weight percentage. The preparation method comprises the steps as follows: the components are mixed to form a mixture according to the formulation, and then the mixture is stirred, settled, cut and later maintained for 10 to 12 hours under high temperature of 180 to 200 DEG C and high pressure of 10 to 12 standard atmospheric pressures so as to obtain the sand-air impervious concrete masonry block. The invention has the advantage that a certain proportion impervious materials are added into the material of the masonry block so as to manufacture the masonry block provided with the impervious capability; after the masonry block is adopted as the single material for walling, then the block is provided impervious capability after walling by the block. The sand-air impervious concrete masonry block can be regarded as the novel walling material without adopting the waterproof material to reach the waterproof and impervious requirement.

Description

technical field [0001] The invention relates to a concrete block, especially an anti-seepage block of sand aerated concrete, which is mainly used in the outer protective walls of concrete structures, steel structures and wooden structure components in self-insulation and energy-saving buildings, and can also be used in Generally, it is suitable for walls in wet parts such as bathrooms and kitchens on interior walls. Background technique [0002] At present, there are many types of sand aerated concrete blocks in the construction market, but so far there is no sand aerated concrete block (or other wall materials) that can meet the waterproof and anti-seepage requirements as a single building wall material. Sand aerated concrete blocks (or other wall materials) are not waterproof or impermeable after the wall is formed, and the waterproof and impermeable requirements of the building are mainly met by painting waterproof materials. With the continuous improvement of my country...
