Embodiment 1

[0026] A high thermal resistance self-insulating block, such as figure 1 , 2 As shown, including the block body, the block body is provided with five rows of holes, respectively the first, second, third, fourth, and fifth rows of holes, wherein the first, third, and fifth rows of holes Both include two rows of closed first holes, and the two rows of first holes are symmetrically arranged, while the second and fourth rows of holes each include a row of closed second holes and two rows of third holes with openings at one end, two rows The third holes are respectively arranged on both sides of the second hole, and the openings of the third holes are far away from the second hole, and the length of the third hole is half of the length of the second hole; the block body is mixed with various ingredients Compression molding.

[0027] The first, second, third, fourth and fifth rows of holes gradually narrow in width along the height direction.

[0028] When building, such as ima...

Embodiment 2

[0039] The difference between this embodiment and Example 1 is that its proportioning materials account for different percentages of the total mass: the proportioning materials of this embodiment account for the percentage of total mass as follows:

[0040]

[0041] In order to better illustrate the technical scheme of the present invention, an example is given for illustration:

[0042] In the embodiment of the present invention, such as figure 2 As shown, the size of the block is 390mm×280mm×190mm, the five rows of holes are all rectangular, and the long side is perpendicular to the thickness direction; the five rows of holes are arranged symmetrically along the thickness direction, and the first and fifth rows are closed holes of 40mm×160mm. 3 rows are closed holes of 30mm×160mm; there is a row of holes in the middle of rows 2 and 4, the size is 30mm×170mm, and there are two open holes on both sides, the size is 30mm×80mm. The size of the closed hole after the opening ...

Abstract

The invention discloses a high-heat-resistance and self-thermal-insulation concrete block and a material formula thereof, and belongs to the technical field of building materials. The high-heat-resistance and self-thermal-insulation concrete block comprises a concrete block body, wherein five rows of holes are formed in the concrete block body, the first row of holes, the third row of holes and the fifth row of holes all comprise two columns of first closed holes; the two columns of first holes are symmetrically arranged, the second row of holes and the fourth row of holes all comprise one column of second closed holes and two columns of third holes with openings in one ends, and the material formula comprises water, cement, ceramsite, slag, pulverized fuel ash and rock wool (the last terms are industrial wastes). The high-heat-resistance and self-thermal-insulation concrete block has high heat resistance and self-thermal insulation property, thereby being in thermal insulation performance; meanwhile, the high-heat resistance and self-thermal insulation concrete block is high in production efficiency, energy-saving and environmental-friendly, and is low in price; meanwhile, the compressive strength of the high-heat-resistance and self-thermal-insulation concrete block can meet the requirement of a load-bearing concrete block of a dual-layer concrete body structure of a rural residential building.

Description

technical field [0001] The invention relates to a high thermal resistance self-insulation block and its material formula, belonging to the technical field of building materials. Background technique [0002] In recent years, environmental protection and sustainable development have put forward new requirements for high efficiency and energy saving of buildings, especially for masonry buildings in villages and towns located in the severe cold regions of Northeast China. For building energy saving standards of 65%, "Rural Housing Energy Conservation Design Standards - Draft for Comments" 》Gives the limit value of heat transfer coefficient of rural housing enclosure structures in severe cold and cold areas, for example, the heat transfer coefficient of external walls in severe cold (A) area is not greater than 0.40W / (m 2 · K). If the thermal conductivity of clay bricks is 0.40W / (m·K), then in order to meet this energy-saving requirement, the thickness of the required wall shou...
