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 ...…
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...…
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...…
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...…
Production of the Graphene Powder Graphene is a single-atom thin sheet of carbon which is extremely robust. Its hexagonally-connected carbon atoms provide it with strength and a very thin, lightweight form. This material is becoming a popular choice ...…
Because of boron's involvement in cell growth, symptoms of boron deficiency are expressed at the growing tips of the root or shoot and generally include stunting and distortion of the growing tip that can lead to tip death, brittle foliage, and yello...…
Surveys for classification of vessels are currently carried out by human specialists who move through the ships’ many different tanks to check whether the metal hull has started to corrode– and, if so, how serious the damage is.In co…
