Embodiment Construction

[0025] like figure 1 , figure 2 and image 3 As shown, the autoclaved fly ash semi-blind porous brick is provided with two square hollow holes 2 in the middle of the brick 1; several semi-blind circular holes 3 are arranged around the two square hollow holes 2; The length direction of the orifice 4 of the square hollow hole 2 at the bottom has a slope 5, the angle a between the slope 5 and the inner wall is 125°, and the distance h between the bottom of the semi-blind circular hole 3 and the bottom of the brick 1 is 10mm.

[0026] The specifications of the brick: the length w is 235-245mm, the width x is 185-195mm, and the height y is 110-120mm; the orifice specification of the square hollow hole on the front of the brick: the length d is 65-75mm, and the width c is 50 ~55mm; orifice specification of the square hollow hole at the bottom of the brick: the length f is 45~50mm, the width e is 5~10mm; the diameter r of the semi-blind circular hole is 28~32mm, the semi-blind arr...

Abstract

The invention relates to an autoclaved fly ash semi-blind porous brick, which is characterized in that the centre of the brick is provided with two square hollow holes, a plurality of semi-blind round holes are arranged at the periphery of the two square hollow holes, and the hollow ratio of the brick is 30-35%; the brick comprises the components of fly ash, bottom slag, lime powder and fine sand, and the weight percentage of each component is as follows: 40-50% of fly ash, 30-35% of bottom slag, 5-12% of lime powder and 10-18% of fine sand. The invention further relates to a preparation method of the autoclaved fly ash semi-blind porous brick. The invention has the advantages of lower production cost of the brick and higher compressive strength, low dry shrinkage and preferable durability of the produced brick.

Description

1. Technical field [0001] The invention relates to a semi-blind porous brick, in particular to an autoclaved fly ash semi-blind porous brick and a preparation method thereof. 2. Background technology [0002] At present, in the production process of autoclaved fly ash porous bricks used in building filling wall materials, fly ash, quicklime, cement, fine sand, etc. are mostly used as raw materials, and are mixed, digested, formed, and maintained according to a certain ratio. etc. to produce autoclaved fly ash porous bricks; the autoclaved fly ash porous bricks made have several hollow holes on the bricks, and this autoclaved fly ash porous bricks exist to varying degrees in the application of building filling walls The following defects: relatively high cost, low compressive strength, insufficient durability and many other problems, which affect and restrict the large-scale application of fly ash bricks in construction projects. 3. Content of the Invention [0003] In vie...
