“…The continuous of C-S-H gel within a pore structure contribute to strength development in concrete [14]. Results achieved in recent study show an increase in compressive strength as curing age increased due to the formation of C-S-H gel [18]. In line with this current study; development of additional C-S-H gel was observed when clay brick waste was used in mortar and concrete in an experimental study [19].…”

The reuse of waste materials in civil engineering projects has become the topic for many researchers due to their economic and environmental benefits. In this study, brick dust waste (BDW) derived from cutting of masonry bricks and demolition waste which are normally dumped as land fill is used as partial replacement of cement in a concrete mix at 10%, 20% and 30% respectively, with the aim of achieving high strength in concrete using less cement due to the environmental problems associated with the cement production. To ascertain the effects of BDW on the consistency and mechanical performance of concrete mix, laboratory investigations on the workability of fresh concrete and the strength of hardened concrete were carried out. Slump and compaction index test were carried out on fresh concrete mix and unconfined compressive strength (UCS) test and tensile strength test were conducted on hardened concrete specimen after 7, 14 and 28 days of curing. The results showed high UCS and tensile strength with the addition of 10% BDW to the concrete mix, hence achieving the set target in accordance with the relevant British standards. A gradual reduction in strength was observed as BDW content increases, however, recording good workability as slump and compaction index results fell within the set target range in accordance with relevant British standards. Findings from this study concluded that BDW can partially replace cement in a concrete mix to up to 30% igniting the path to a cleaner production of novel concrete using BDW in construction work.

Concrete is known to be is the most used construction material throughout the world to meet the needs of major infrastructure projects. Its superior structural strength and stability are mainly due to the presence of binding material cement. The production of cement accounts for large amounts of carbon-di-oxide throughout the world. This percentage is estimated to rise further increasing the CO2 levels in the coming future. It may not be avoided entirely, but it can be partially reduced by using supplementary cementitious materials. Fly ash is one such material that can be partially replaced with cement, with altering the strength of conventional concrete. Fly ash ranging from 0% to 50% was replaced with cement and the concrete was evaluated for compressive strength. Curing is also an essential factor in order to achieve the desired strength to the concrete. The heat produced during the hydration process needs to be brought down by curing, to maintain the favourable conditions for the surface of concrete. Various curing methods have been adopted, such as complete water immersion curing, 3-day water immersion curing, wet burlap curing, compound curing, and open-air curing. These specimens were tested for compression at 3 days, 7days and 28 days. It is concluded from the experimental results that at all ages, 20% fly ash replacement resulted in better strength. Complete water immersion curing proved to give better strength results, followed by wet burlap curing, 3-day immersion curing, compound curing, and open-air curing.
