Described a kind of high strength rhombspar aerated-block is characterized in that:

The preparation method comprises the following steps:

(1) get by weight the rhombspar fragmentation, cross the 60-100 mesh sieve, then add by weight alkyl glycoside, Starso, and suitable quantity of water, stir after 10-15 minute under 120-150 rev/min, fire 2-4 hour under 1100-1200 ℃ after, obtain the modification dolomite powder standby;

(2) oxidized paraffin wax soap, Vltra tears sodium, borax, Sunmorl N 60S are mixed by weight, add suitable quantity of water, stir after 5-7 minute under 30-40 ℃, then add cement, stir, then add the mixed cement slurry;

(3) by gained mixed cement slurry and modification dolomite powder and all the other raw material blendings, add suitable quantity of water, the moulding that pours into the mold, after at 40-50 ℃ of lower precuring 3-5 hour, the demoulding, handling to cutting part cuts, and obtains the building block base;

(4) the building block base is put into to reactor steam press maintenance 10-15 hour, put in storage finished product and get final product.

Beneficial effect of the present invention is: increased the intensity of aerated bricks by the rhombspar modification, the durable heat-insulation life-span is long.

Embodiment

A kind of high strength rhombspar aerated-block, it is that raw material by following weight parts (kg) makes: rhombspar 40, oxidized paraffin wax soap 0.03, Vltra tears sodium 1.1, borax 1.5, Sunmorl N 60S 0.8, cement 10, methyl acrylate 0.1, saltcake 1, sugared calcium 0.1, soda ash 0.1, Sodium Benzoate 0.2, potassium hydroxide 0.3, zinc powder 0.1, organic silicon emulsion 0.1, alkyl glycoside 0.005, Starso 0.46.

Described a kind of high strength rhombspar aerated-block,

The preparation method comprises the following steps:

(1) get by weight the rhombspar fragmentation, cross 60 mesh sieves, then add by weight alkyl glycoside, Starso, and suitable quantity of water, under 150 rev/mins, stir after 10 minutes, fire 3 hours under 1200 ℃ after, obtain the modification dolomite powder standby;
