Example Embodiment

[0062] Example 1

[0063] An energy-saving and 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 is ≥80% of the volume of the whole block.

[0064] The said components also include water reducer, water repellent and catalyst, their weight ratios are respectively: 0.43%, 0.2% and 0.43%.

[0065] The left and right sides of the energy-saving and self-heating ceramsite block are provided with a core hole 8 communicating with two sides.

[0066] The production method adopted is: it includes 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 the ceramsite 320 kg of 400 grade (ceramsite bulk density 400kg / m3), so that the volume o...

Example Embodiment

[0091] Example 2

[0092] The energy-saving self-insulating ceramsite block and its manufacturing method and molding die are basically the same as those in Example 1, except for 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 proportion of materials.

[0093] Example 2 According to the requirement that the bulk density of the block product is 700kg / m3, first weigh 255 kg of 300-class (ceramsite bulk density 300kg / m3) ceramsite, so that the volume of the ceramsite accounts for 85% of the block volume;

[0094] The proportion 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 the cement was weighed according to the weight ratio: 175 kg, accounting for 25%; fly ash: 196 kg, accounting for 28%; fib...

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...
