“…It is estimated that, a single kilogramme of palm oil results in 4 kg of dry biomass [20]. The Malaysian oil palm industry generates 3 million tons of POFA in the year 2007 and it is estimated that production rate will increase due the expansion of oil palm sector [21]. Several researchers [22][23][24] have studied the usefulness of POFA as a supplementary cementitious material for enhancing mechanical performance as well as durability of concrete products.…”

This paper investigates the creation of high-density impermeable concrete. The effect of the "cement, fly ash, and limestone" composite binders obtained by joint grinding with superplasticizer in the varioplanetary mill on the process of structure formation was studied. Compaction of structure on micro-and nanoscale levels was characterized by different techniques: X-ray diffraction, DTA-TGA, and electron microscopy. Results showed that the grinding of active mineral supplements allows crystallization centers to be created by ash particles as a result of the binding of Ca(OH) 2 during hardening alite, which intensifies the clinker minerals hydration process; the presence of fine grains limestone also leads to the hydrocarboaluminates calcium formation. The relation between cement stone neoplasms composition as well as fibrous concrete porosity and permeability of composite at nanoscale level for use of composite binders with polydispersed mineral supplements was revealed. The results are of potential importance in developing the wide range of fine-grained fiber-reinforced concrete with a compressive strength more than 100 MPa, with low permeability under actual operating conditions.

“…However, producing SCC with high workability and desired strength requires the addition of expensive chemical additives to reduce the binder content of the cementitious material and to raise the cost of the SCC and the higher CO 2 emissions as per traditional concrete. Furthermore, greater consumption of Portland cement (PC) in the SCC mix design concludes increased hydration heat and higher autogenous shrinkage . However, the high cost of SCC, which is caused by the use of a higher volume of PC and chemical additives, can be seen as a disadvantage.…”

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.
