Lightweight foamed concrete is usually prepared by introducing foaming agents such as hydrogen peroxide and plant surfactants into cement paste to form high pores and voids in the matrix. A foaming agent is a material that facilitates foam formation,...…
What is foamed concrete?Lightweight foamed concrete is usually prepared by introducing foaming agents such as hydrogen peroxide and plant surfactants into cement paste to form high pores and voids in the matrix. A foaming agent is a material that fac...…
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...…
What is Foaming agent?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 properti...…
A disparity in the water release from the foam concrete samples was noticed for two types of foaming agents. The rapid outflow of water from the models was observed in the foam concrete with the protein foaming agent for the curing conditions applied...…
Not only does the density affect the compressive strength and thermal conductivity, but it also affects the foam concrete structure. The synthetic or protein nature of the foaming agent contributes to differences in air-void distribution and, as a re...…
The analysis of the thermal conductivity dependency on the density detects the linear fit as a best-fitting curve for the considered range of FC densities. The coefficients of the linear fit are depicted. Exceptionally high values of the coefficient ...…
Then, the cement type employed in foam concrete was compared regarding thermal conductivity. The obtained results for foam concrete with the considered Buildings 2022, 12, 1176 17 of 20 densities below 500 kg/m3 revealed the beneficial effect of CSA ...…

This study aims to investigate the ultra-lightweight foam concrete of rarely studied density ranges (200–500 kg/m3), looking for the most favorable configuration of properties of such feasible insulating material: compressive strength and thermal con...…
Thermal properties of foam concrete can be improved by several types of additives, i.e., coir fiber, which applied resulted in higher heat capacity and lower thermal conductivity of the FC, as well as polypropylene fibers, which allowed for the reduc...…
Furthermore, by-products and wastes are utilized in geopolymer foam concrete. Considering the mentioned properties, foam concrete may create an alternative for the commonly used materials such as extruded polystyrene (XPS) boards, which utilization r...…
The world's largest graphite deposits are mainly located in China, Europe, Mexico, the United States, Austria, Brazil, Canada, Germany, and Madagascar. According to the U.S. Geological Survey, the current world graphite resource reserves are…
Concrete is a mixture of a graded aggregate, sand, water, and cement. It is necessary to study the influence of concrete components on the effect of the high-efficient superplasticizer in order to give full play to their due effect.…
What is Iron oxide?Iron(III) oxide or ferric oxide is an inorganic compound with the formula Fe2O3. It is one of the three main oxides of iron, the other two being iron(II) oxide (FeO), which is rare, and iron(II, III) oxide (Fe3O4), which also occur...…
