“…These are naturally ready to use with mechanical treatment, i.e., crushing and sieving. Mostly, natural LWAs are of volcanic origin, e.g., pumice and scoria [11,12]. Thus, they are only found in a few areas of the world.…”

“…Zulkifeli and Saman [31] studied the compressive and flexural strength of mortar using EPA. It was found that the modulus of rupture and strength was increased at a temperature of 200 • C. Karatas [12] studied the thermal resistance of self-compacting mortars (SCM) that were developed by normal and LWAs such as EPA and pumice. SF and FA were used as mineral additives.…”

Lightweight aggregate concrete (LWAC) exhibits the advantages of thermal insulation, reduces energy consumption building costs, improves building efficiency and easy construction. Furthermore, the utilization of industrial wastes in concrete is advantageous in terms of environmental sustainability. In order to explore this, several researchers investigated the idea of integrating industrial wastes in LWAC. However, the lack of knowledge regarding the performance of industrial waste-based lightweight aggregate concrete hinders the adaptation of this concept and application of LWAC in the construction sector. Therefore, this paper summarizes the research in relation to the sustainable LWACs containing oil palm shell (OPS), lightweight expanded clay aggregate (LECA), vermiculite, perlite, pumice and sintered fly ash as lightweight aggregate, along with industrial wastes and strength-enhancing additives (viz. fibers, polymers, etc.). Firstly, desirable physical, chemical, morphological and mineralogical characterization of different lightweight aggregates are presented, and then a comprehensive overview on fresh, hardened, durability and thermal properties of LWAC incorporating industrial wastes are discussed in comparison with normal weight concrete. The review also highlights the current challenges and suggests the research gaps for further development of eco-friendly LWAC. It is concluded that vermiculite, perlite, pumice, OPS, sintered fly ash and LECA with some suitable industrial waste materials have the potential to be used in the construction sector. Moreover, LWAC with industrial waste has 50–65% lower carbon emission (kg CO2 eq/m3) in the environment. The scientific contribution of this paper provides insights into different LWACs and the knowledge base for future research and paradigm shift of using LWACs as more common alternative building materials.

“…The occurrence of spalling resulted from two main reasons which are the presence of a thermal gradient and water vapor motion caused by temperature exposure. 16,17 Spalling results in concrete scaling and could reduce its cross-sectional area. 2 Behnood and Ghandehari 18 probed the tensile and CS of HSC with and without PP fibers after heating up to 600 C. This study used water-to-cement ratios of 0.4, 0.35, and 0.3 and PP fibers of 0, 1, 2, and 3 kg/m 3 .…”

In this paper, the residual mechanical properties, mass loss, and cracking behavior of hybrid‐fiber‐reinforced high‐strength concrete (HFRHSC) containing 0%, 30%, and 60% ground granulated blast furnace slag (GGBFS) in normal and high temperatures have been investigated. Chopped aramid and steel fibers at 0%, 0.5%, and 1% by volume, either individually or in different combinations, were used to reinforce the HSC. In total, 24 different mix proportions were designed. The experimental results showed that the residual compressive strength of the majority of specimens increased at 400°C while this property of all of them decreased at 800°C. Also, the test indicated that the use of GGBFS did not reduce flexural and compressive strength of HSC significantly, and in some mixed designs, the presence of GGBFS slightly increases the strength. Moreover, another result that can be inferred is that although the utilization of hybrid fibers in concrete increases flexural strength, it may decrease its compressive strength. In addition, the residual flexural strength of most specimens was reduced at 400°C, but this property of all samples decreased at 800°C. The results showed that the simultaneous presence of GGBFS and hybrid fibers can improve the flexural strength of most specimens at different temperatures.

“…The Al 2 O 3 composition makes it heat‐resistant and fire‐resistant, and the SiO 2 content in the rock gives it an abrasive property. The use of pumice as an aggregate or mineral additive in the manufacture of SCC can serve as an attractive way of producing lighter‐weight, environmentally friendly, and cost‐effective concrete . Steel fibers were proved to have the potential to enhance mechanical properties of concrete such as postcracking energy absorption capacity and enhancing the ductility.…”

This study reports the results of high temperature effects on the properties of steel fiber reinforced self-compacting concrete (SFRSCC) fabricated by replacing cement with ground pumice powder (GPP) as mineral additive at different substitution rates. The mixtures had the same amounts of steel fiber and the binding material with constant water to binder (w/b) ratio of 0.37. In this context, five SFRSCC series were prepared by replacing Portland cement (PC) with 5, 10, 15, and 20% of GPP including the control mix. Sixty cube samples with a dimension of 150 × 150 × 150 mm were fabricated and exposed to curing aged 3, 7, 28, and 90 days to conduct compressive strength tests and a total of 100 × 100 × 350 mm 18 beam samples cured at 28 days were fabricated to perform the flexural strength tests. Durability tests were performed on the 18 cube samples of 100 × 100 × 100 mm subjected to water curing at 28 days. In addition, the relation between the compressive strength and Ultrasonic Pulse Velocity (UPV) of SFRSCC samples was compared aged 1, 3, 14, and 28 days. Samples of SFRSCC were subjected to the temperatures of 200, 400, 600, and 800 C after being cured at 28 days then cooled to room temperature before conducting tests. The results revealed that the compressive strength of all SFRSCC mixes enhanced at 200 C by 5.34 and 3.55% for control and GPP10 mixes respectively. The strength loss of mixes incorporating GPP is about 60% at 800 C.
