Properties and behavior of light hydrophobic concrete

Abstract

In concrete mixing plan, we usually encounter a combination of aggregates including sand, the amount of cement, which is actually the criterion of concrete grade, and the volume of water consumed. Changes in the quality and quantity of these components actually create the usual types of concrete. But the attitude that formed the basis of this research is based on the change in the nature of the components of the concrete mixing design. Removal of water and cement from the mixing plan and replacement of polymeric materials as well as the use of mixed LECA aggregates instead of aggregates is the basis of this research. In this paper, by examining and selecting LECA grain style and pre-treatment (hydrophobicity and coupling), in a constant ratio of resin, concrete samples were selected from three dimensional categories. After making the samples, flexural strength test was performed on them and the results were analyzed. Various compounds and processes have so far been proposed in the lightweight concrete mixing scheme. The distinctive point of this study is the use of lightweight expanded clay concrete with heat-treated acrylic polymer (crosslinking constituents) and related coupling agents. It is also important to select and apply the right amount of hydrophobic nanoparticles for hydrophilic surface hydrophobicity. Hydrophobicity was possible due to the non-polar nature of the acrylic polymer and the use of hydrophobic nanomaterials.

Effect of gelatin powder, almond shell, and recycled aggregates on chemical and mechanical properties of conventional concrete

“…The findings indicate that the high-water absorption of the aggregates and the weak areas created by the mortar adhering to the old interface is primarily responsible for the RAC's deterioration in terms of its mechanical properties. The sturdiness of RAC likewise was explored, and the outcomes show that the higher the reused total (RA) content, the mortar content appended to the RA, and the W/C (water-to-ash ratio), the more regrettable the strength of RAC [21][22][23]. The use of almond shell and gelatin powder to mix with concrete lacks sufficient information regarding the properties of the fresh and hardened shell and gelatin powder, as can be seen from earlier literature.…”
