Anonymous users2024-02-16No, light aggregate concrete.
It has the characteristics of light weight, thermal insulation and good fire resistance. Compressive strength of structural light aggregate concrete.
Up to 70 megapascals, compared with the same grade of ordinary concrete, can reduce the weight of 20 30% or more, structural insulation dry mix composite light aggregate concrete is a wall material with good thermal insulation performance, its thermal conductivity.
for the tile (m * open), only 12-33% of ordinary concrete. Light aggregate concrete has good deformation properties and elastic modulus.
Lower. In general, shrinkage and creep are also larger. The modulus of elasticity of light aggregate concrete is directly proportional to its bulk density and strength.
The smaller the bulk density, the lower the strength, and the lower the modulus of elasticity. Compared with ordinary concrete of the same grade, the elastic modulus of light aggregate concrete is about 25 to 65% lower. 1] Light aggregate concrete is widely used in industrial and civil construction and other projects, which can reduce the weight of the structure; improve the seismic performance of the structure; Save the amount of materials used; Improve the efficiency of component transportation and hoisting; Reduced foundation load and improved building functionality (insulation, fire resistance, etc.).
Therefore, in the 60s and 70s of the 20th century, the production and application technology of light aggregate concrete developed rapidly, mainly in the direction of light weight and high strength. Since the 50s, China has been developing light aggregate and light aggregate concrete, which are mainly used for basement backfilling, roof insulation, roof slope finding, and floor heating backfill of industrial and civil buildings.

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.
Do you have any other questions? I can go on and on for you to answer 3I hope this service can help you, you can click on my avatar to follow me, and if you have any questions in the future, you can consult me again, and look forward to serving you again.

Anonymous users2024-02-13The difference between light aggregate branched concrete and foamed concrete is that the price of light aggregate concrete is about yuan cubic meter, while the price of foamed concrete depends on its strength grade and use.
For example, if you use the backfill of the garage roof, the foamed concrete may be 550 yuan per cubic meter, including cement, anti-crack composite and labor costs.
In general, the difference between light aggregate concrete and foamed concrete lies in the difference in their raw materials and processes. Lightweight aggregate concrete mainly uses lightweight aggregates, while foamed concrete uses foaming agents to create foam. The difference between these two types of concrete also reflects their performance and application.

Anonymous users2024-02-12Foam concrete is cheaper than light aggregate concrete.
1. Data consumption per cubic meter of light aggregate concrete approximate matching instance: calculated according to JGJ51-2002 specification design. Cement:
Sand: ceramsite = 340 kg: 720 kg:
166 kg. At present, the approximate market of various materials is as follows: cement 550 yuan (yuan kg), river sand 180 yuan (yuan kg), ceramsite 260 yuan Ming Zhaobi cubic meter (particle size 5-25 mm, bulk density 400 kg cubic meter, yuan kg).
The material of one cubic creel ceramsite concrete ** is 340 * = yuan.
2. Foam concrete. The garage roof is backfilled with foam concrete, which typically has a compressive strength of MPA. The amount of cement used is about 550 kg per cubic meter.
Guess which data and construction cost per cubic meter of foam concrete are summarized as follows: 550 kg per cubic meter of cement, 550 * 10 yuan per cubic meter of anti-crack composite according to your labor **.

Anonymous users2024-02-11Summary. 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

Anonymous users2024-02-10Is LC15 light aggregate concrete the same as foamed cement?
Of course not. Light aggregate concrete: mixed spike concrete with a dry apparent density of no more than 1950kg m3 prepared with light coarse aggregate, light sand (or ordinary sand), cement and water.
LC15 belongs to one of them, that is, concrete with a strength class of 15MPa. Foamed aquarium early mud: also called foamed concrete, envy foam concrete, is a new type of lightweight insulation material containing a large number of closed pores formed by the foaming system of the foaming machine through the foaming system of the foaming machine.
It belongs to the bubble-like thermal insulation material, and the outstanding feature is to form a closed foam hole inside the concrete, so that the concrete is lightweight and insulated.
The core problem is the stability of the water absorption rate of light aggregate, if it is stable, it can increase the amount of water to be absorbed by the aggregate when batching, and it can also ensure the performance of light aggregate concrete. >>>More
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.
1. Determine according to the method of how to deal with it. The standard of bearing capacity in the construction preset is generally 360kg m2, and the slag of autoclaved curing cement blocks belongs to construction waste, and as long as it can meet the bearing capacity standard, it can be considered suitable and used as a supplementary material. >>>More
