What is Concrete Foaming Agent?"Foamed concrete" is made by adding a foaming agent into a mixed mortar in a truck mixer. Foamed concrete is a nonstructural void filler that excavators can dig out. It is used for trench backfill and similar applicatio...…
When constructing monolithic structures made of foam concrete, it is necessary to observe the temperature conditions of holding and drying and the design features of formwork systems. The greatest problems arise at low positive and, especially, at ne...…
An important factor in concrete foam technology is temperature. First, this is the temperature of the outside air and the foam concrete mix when laying. When the temperature drops below +15° C, the time of setting of cement, the set of plastic, and f...…
An important place in the technology of foam concrete is the method of preparing a foam concrete mixture. There is separate and joint technology. For both methods, the structural and technological parameters of the mixing equipment used significantly...…
The dependences of foam concrete properties on various factors, which are divided into four groups, are considered. The dependence of physical and mechanical properties on the properties of materials, conditions for maintaining foam concrete, on the ...…
What is Concrete Foaming Agent?Lightweight foamed concrete is usually prepared by introducing foaming agents such as hydrogen peroxide and plant surfactants [10, 11] into cement paste to form high volumes of pores and voids in the matrix—foaming agen...…
Preformed foam from the synthetic foaming agent was added into the geopolymer paste in various ratios of geopolymer paste to the foaming agent volume of 1:0.50, 1:0.67, 1:0.75, 1:1.00, 1:1.33, 1:1.50, and 1:2.00. Formerly, the foaming agent was perfo...…
Based on type, the market for foam concrete is further segmented into synthetic and protein foaming agents. Based on application, the market for foam concrete is further segmented into infrastructure, residential, industrial, garden, pavements, and o...…
What is Cement foaming agent?Foam concrete is commonly used in building materials due to its cheap Price and suitable lining properties. In addition, foam concrete helps minimize weight and construction costs because it has a low density. These are a...…
The foaming agent is an indispensable component in the preparation of foam concrete by using prefabricated foams. This study used four types of foaming agents to prepare foam concrete. Effect of the foaming agent on the properties of fresh and harden...…
The physical properties of the foam concrete are related to the dry density. The variation is seen in the tabulation given in the table below. Typical Properties of Foamed Concrete in its Hardened State: The thermal conductivity of foam concrete rang...…
The coarse aggregate or other replacement for coarse cannot be used. This is because these materials would sink into the lightweight foam. Mix Details of Foam Concrete: The foam concrete properties depend upon the following factors: The volume of the...…
Molybdenum disulfide may cause electrochemical corrosion of metals when used in humid environments, and its performance will be affected at low temperatures and humid climates. Graphite can also be used as a solid additive, but molybdenum disulfide h...…
Moreover, the content, shape, structure, and distribution of air pores in foam concrete mainly relied on the properties of prefabricated foams, cement pastes, and the interaction between foams and cement pastes. Previously, most of the research focus...…
Using titanium and boron oxides as raw materials and carbon black as a reducing agent, a long-term high-temperature carbon reduction process is conducted in a carbon tube furnace. The purity of the synthesized titanium diboride powder depends on the ...…
