“…The majority of fly ash particles are spherical in shape and range in size from 0.5 to 100 micrometers [35]. Tareq S. al-Attar1 et al in 2019, studied lightweight concrete's water absorption [36]. The mixture's ingredients were combined in a mechanical mixer with a capacity of 20 liters.…”

“…The water absorption that resulted at 28 days revealed that fly ash FA50 and FA60 are better lightweight's concretes than FA70. Therefore, it is reasonable to recommend that the approval age should be increased from 28 days to a higher age or that the concrete be strengthened with fiber reinforcement [36]. Suhad M. Abd and D. K. Ismail in 2019, studied the effects of different aggregates on the mechanical properties, which included, compressive strength, fresh and hardened density, and also elasticity modulus and they were tested in this study [37].…”

Conventional concrete is recognized for its high density, which leads to a higher cost of building foundations and columns. Recently, many efforts have been made to produce lower density concrete with acceptable and applicable mechanical properties. One option can reduce the density of the conventional concrete by using partial or total replacement of porcelanite instead of natural gravel. Porcelanite aggregate concrete can be prepared by adding different ratios of porcelanite and several other additives to the mortar, depending on the required density of the prepared porcelanite concrete. This study aims to assess porcelanite aggregate concrete components, manufacturing methods, and features of porcelanite aggregate concrete. Furthermore, this literature review aims to appraise and provide a complete vision of the testing program, including compressive strength, density, porosity, splitting tensile strength, and water absorption of porcelanite aggregate concrete. Also, this paper focuses on studying the development and applications of the porcelanite aggregate concrete, which will be presented in detail through this study.

Several research studies have been conducted on the usage of nanoscale silica particles in concrete, based on the success of employing silica fume as an active pozzolan in concrete. The impact of several doses of nanosilicas (NpSs) in powder having a certain surface area of 160 m2/g and two particle sizes of porcelanite rock on the mechanical characteristics of lightweight porcelanite aggregate concrete was investigated. The addition of NpS particles significantly improved the workability of mixes, according to the results. The compressive strength of samples was influenced by NpS, with higher doses of NpS resulting in greater improvement. Porcelanite aggregate concrete’s compressive strength was unaffected by a modest percentage of different NpSs. NpS had an effect on the samples. Flexural strength also improved at all NpS dosages. The flexural strength of porcelanite aggregate concrete increased by a low percentage of various NpS.
