Problems solved by technology

Using this method to make blocks will waste a lot of water, electricity and raw materials during the cutting process, which runs counter to energy saving and low consumption
What's more serious is: the noise generated during cutting and the fine dust formed by cutting are very serious for environmental pollution
Especially when splitting from a large block to a block combination block at the beginning, not only the noise and dust pollution are unbearable, but also a large cutting tool and cutting machine equipment must be used

Embodiment 1

[0063] An energy-saving self-insulating ceramsite block, its components mainly include ceramsite, cement, fly ash, water, fiber, and foaming agent; the weight ratios of the components are: ceramsite 45.7%, cement 28.6% , fly ash 15.7%, water 4%, fiber 0.92%, foaming agent 4%; and the volume of the ceramsite component ≥ 80% of the volume of the entire block.

[0064] The composition also includes a water reducing agent, a waterproofing agent and a catalyst, and their weight ratios are respectively: 0.43%, 0.2% and 0.43%.

[0065] The left and right sides of the energy-saving self-insulating ceramsite block are provided with a core hole 8 that communicates with both sides.

[0066] The production method that adopts is: it comprises the following steps:

[0067] 1) Material selection and measurement:

[0068] According to the requirement that the bulk density of the block product is 700kg / m3, first weigh 320 kg of ceramsite of grade 400 (ceramsite bulk density 400kg / m3), so tha...

Embodiment 2

[0092] The energy-saving self-insulating ceramsite block of Example 2 and its production method and forming mold are basically the same as those of Example 1, the difference is the material ratio of the self-insulating ceramsite block and the selection of materials in step 1) of the production method, In the measurement, the measurement of raw materials is changed according to the ratio of materials.

[0093] Embodiment 2 is 700kg / m by the bulk density of building block product Requirement, at first weigh 255 kg of ceramsite of 300 grades (ceramsite bulk density 300kg / m ), make the volume of ceramsite account for 85% of block volume;

[0094] The ratio of each component is: ceramsite 36.4%, cement 25%, fly ash 28%, fiber 0.5%, water 5%, foaming agent 4%, water reducing agent 0.3%, catalyst 0.2%, waterproofing agent 0.1 %.

[0095] Then according to the weight ratio, cement: 175 kg, accounting for 25%; fly ash: 196 kg, accounting for 28%; fiber: 3.5 kg, accounting for 0.5%; wa...

Abstract

The invention relates to an energy-saving self-heat-insulation ceramsite building block and its manufacturing method and forming mould. The energy-saving self-heat-insulation ceramsite building block is made of, by weight, 35-50% of ceramsite, 20-29% of cement, 15-30% of coal ash, 0.5-1% of fibers, 2-5% of foaming agent, 0.3-0.5% of water reducing agent, 0.1-0.3% of waterproof agent and 0.2-0.5% of catalyst, wherein the volume of the ceramsite accounts for more than 80% of that of the whole building block. The manufacturing method of the building block includes steps of material selecting, metering, stirring, pouring, vibrating, steaming, tube drawing for demoulding, cutting forming and stacking for rest. The forming mould of the building block can be used for once forming of multiple medium-sized rectangular ceramsite building blocks, and each building block can be conveniently cut into standard small ceramsite building blocks. The energy-saving self-heat-insulation ceramsite building block is high in ceramsite content and has the advantages of light weight, warm retention, heat insulation, sound insulation, sound adsorption, low water adsorption, fire resistance, freezing resistance, quake proofing, corrosion resistance and the like.

Description

technical field [0001] The invention relates to the field of construction, in particular to an energy-saving self-insulating ceramsite block, a manufacturing method thereof and a molding die. Background technique [0002] Governments of various countries attach great importance to how to improve the energy-saving indicators and environmental protection performance of building materials. Therefore, how to realize the self-insulation, heat insulation, sound insulation, waterproof, shockproof and other functions of wall materials and reduce the pollution generated in the production process is a very meaningful and very important subject. [0003] Ceramsite has excellent properties, such as low density, high cylinder compressive strength, high porosity, high softening coefficient, good frost resistance, and excellent alkali-aggregate reactivity. Especially because of its low density, porous interior, relatively uniform shape and composition, and certain strength and firmness, c...
