What is the difference between light aggregate microporous concrete and foam concrete

According to the concept defined by Professor Wang Hongzhen, an academic definition of microporous concrete, the main differences between light aggregate microporous concrete and foam concrete: 1. Light aggregate is aggregate, and cement stone is microporous structure with a pore diameter of about 1mm; However, foam concrete has no light aggregate aggregate and the pore size of matrix foam is more than 1mm. 2. Light aggregate microporous concrete is mostly made of micro-expansion fast-hardening cement, with very small shrinkage, which is more suitable for manufacturing wall products; Ordinary foam concrete is made of ordinary Portland cement, which has a large dry shrinkage.

The difference between light aggregate microporous concrete and foam concrete is mainly their composition.

Light aggregate microporous concrete contains pumice, porosyl and porous rock, pumice soil, volcanic muck and porous rock, etc.

Foam concrete is the addition of a foaming agent to conventional concrete production.

Light aggregate concrete refers to the dry surface density that is prepared for aggregate with light coarse aggregate, light sand (or ordinary sand) and the like.

Cement concrete greater than 1900 kg is also called porous aggregate light concrete.

Foam concrete is to fully foam the foaming agent mechanically through the foaming system of the foaming machine, and mix the foam and cement slurry evenly. Then, through the pumping system of the foaming machine, cast-in-place construction or mold forming, a new type of lightweight thermal insulation material containing a large number of closed pores is formed by natural curing.

The main difference between light aggregate microporous concrete and ordinary light aggregate concrete is that its cement-stone matrix is also a microporous structure.

One plus light aggregate and one with foaming agent.

Hello, I am happy to answer for you. Foam slow or concrete is not light aggregate concrete, light aggregate concrete is the use of lighter aggregate material (such as ceramsite,) instead of ordinary sand and gravel aggregate, because the aggregate itself is light, so the concrete weight is light (800--1400kg cubic meters), thermal insulation performance is better, and which potato can be transported to achieve higher strength; Foam concrete has no aggregate.

Summary. 1.Different materials: Light aggregate concrete is the use of lighter aggregates (such as ceramsite, expanded perlite, etc.) instead of ordinary sand and gravel aggregates. Foam concrete is made of conventional aggregates.

2.Different performance: Light aggregate concrete has the characteristics of light weight, thermal insulation and good fire resistance due to the light aggregate itself.

Foam concrete introduces a large number of bubbles into the concrete through physical foaming or chemical foaming, so that the concrete has a light bulk density, low thermal conductivity and other properties.

3.The bulk density is different: the bulk density of light aggregate concrete is 800 1400 kg cubic meters, the strength of light aggregate concrete is higher than that of foam concrete, and the thermal conductivity of foam concrete is higher.

Foam concrete has bubbles, and the bulk density is generally below 600 kilograms of cubic meters is more appropriate.

Advice: Similarities and differences between light aggregate concrete and foam concrete. Thank you!

Hello dear! I've seen your question and I'm trying to sort out the answer, and I'll get back to you in five minutes, so please wait a minute

1.Different materials: Light aggregate concrete is the use of lighter aggregates (such as ceramsite, expanded perlite, etc.) instead of ordinary sand and gravel aggregates.

Foam concrete is made of conventional aggregates. 2.Performance is different:

Due to the light aggregate itself, light aggregate concrete has the characteristics of light weight, thermal insulation and good fire resistance. Foam concrete introduces a large number of bubbles into the concrete through physical foaming or chemical foaming, so that the concrete has a light bulk density, low thermal conductivity and other properties. 3.

The bulk density is different: the bulk density of light round aggregate-resistant concrete cavity rock is 800 1400 kg cubic meters, the strength of light aggregate concrete is higher than that of foam concrete, and the thermal conductivity of foam concrete is higher. Foam concrete has bubbles, and the bulk density is generally below 600 kilograms of cubic meters is more appropriate.

Light aggregate concrete is the use of lighter aggregate material (such as ceramsite,) instead of ordinary sand and gravel aggregate, because the aggregate itself is light, so the concrete weight is light (800-1400kg cubic meters), thermal insulation performance is better, and can achieve higher strength;

There is no aggregate in foam concrete, and the foam agent is generally used to mix the foam and cement slurry to introduce a large number of bubbles into the concrete, so that the concrete has a light bulk density (600-800kg cubic meters), low thermal conductivity and other properties, but the strength is also relatively low.

Foam concrete uses conventional aggregates, through physical foaming or chemical foaming, a large number of bubbles are introduced into the concrete, so that the concrete has a light bulk density, low thermal conductivity and other properties.

Strictly speaking, the compressive strength of light aggregate concrete is stronger than that of foam concrete.

Foam concrete is the highest quality light aggregate, with the lightest bulk density, the longest life, the advantages

Foam concrete is a new type of lightweight thermal insulation material containing a large number of closed pores formed by the foaming system of the foaming machine to fully foam the foaming agent mechanically, and evenly mix the foam with cement slurry, and then carry out cast-in-place construction or mold forming through the pumping system of the foaming machine.

No! But there is something in common! If you want to know more, just ask!

The light concrete that is prepared with light aggregate and the bulk density is not more than 1900 kilograms, also known as porous aggregate light concrete. Its bulk density is less than 800 kilograms, and its compressive strength is less than that of megapascals, and it is mainly used for thermal insulation of envelope structures.

Light aggregate concrete is the use of lighter aggregate material (such as ceramsite,) instead of the general crack banquet block sand and gravel aggregate, because the aggregate itself is light, so the concrete weight is light (800-1400kg cubic meters), thermal insulation performance is better, and can achieve higher strength;

Foam concrete has no aggregate, generally with foam agent mechanical mixing foam and cement slurry mixing method, in the concrete to introduce a large number of bubbles, and the concrete has a light bulk density (600-800kg cubic meters), low thermal conductivity and other properties, but the strength is also relatively low.
