“…Both media will react to decrease production cost because the usage of cement relatively increases in every year. The production of cement, the primary ingredient in concrete [12]. The production cost pressed in order to get the highest advantage but still considered the quality without relieving the ingredients which cause bad quality in the development of high rise building.…”

In world construction, the construction of high-rise buildings almost entirely uses concrete. This study uses fly ash and cement slag as a cement substitute as a reduction in cement requirements. This is due to the limited amount of cement in the market and the binding function of cement and the increasing cement prices. The use of fly ash and cement slag is toxic hazardous waste material that must be handled so that it can be used properly. From the results of the age strength of concrete 1-3 days, the compressive strength of fly ash is higher than that of cement slag but from a mixture of 28 days, it reaches 100% in accordance with the specified standard. In this laboratory test for the use of fly ash and slag cement, 50%, in the future it is necessary to research that the use of fly ash and slag cement can be up to 70% so that the use of fly ash material and cement slag can replace the function of concrete mixed cement as a binder of coarse and fine material to get concrete compressive strength with specified standards. Production costs can be minimized so that if this applied can avoid the company from potential billions/year losses.

“…The original BA was unsuitable for applications as low-reactivity pozzolanic materials in concretes because of their high porosity and large particle sizes. Chao and Kuo [ 2 ] and Clark et al [ 3 ] revealed that the filler effects and pozzolanic activities of industrial ashes depend on their fineness and particle size. Therefore, using a Los Angeles grinding machine (ELE International, Bedfordshire United Kingdom) for 3.0 h at a rotating speed of 33.0 rpm, the original BA was dried to reduce their moisture contents to about 1.0–2.0% (dry basis) and was ground until the particles were less than 15% by mass and retained on a 45 micrometer (µm) sieve.…”

“…The cement industry is becoming a severe threat to ecology due to its emission of carbon dioxide (CO 2 ). The modern world is looking for alternatives so that the environment can be saved for the next generation [ 1 , 2 , 3 , 4 ]. To combat climate change, cement producers have tried to minimize the consumption of Portland cement through the application of supplementary cementitious materials, such as natural pozzolanic materials, to minimize emission of carbon dioxide (CO 2 ) and partly substitute Portland cement in concretes.…”

“…Bagasse ash (BA) is a by-product obtained from the combustion of bagasse for thermal power generation in the sugar manufacturing industry; it has of late been recognized as a low-quality pozzolanic material [ 2 ]. Therefore, most BA is still disposed of in landfills daily, resulting in ecological challenges in the world.…”

Bagasse ash (BA) and rice husk ash (RHA) are by-products from electricity power plants. Ground calcium carbonate waste (GCW) is the by-product of the mining of calcium carbonate (CaCO3) in the color pigment manufacturing industry. Both BA and RHA are classified as low-quality pozzolanic materials, differing from GCW, which contains a high calcium oxide (CaO) content that leads to products equivalent to the hydration reaction. Therefore, GCW is likely able to improve the properties of self-consolidating concrete (SCC) incorporating BA and RHA. This paper discusses the production of green self-consolidating concrete (gSCC) and identifies the benefit of using GCW in gSCC prepared by triple combined GCW (10 and 20 wt%), BA (10, 20, and 30 wt%), and RHA (20 wt%). The results indicate that the majority of the gSCC retain acceptable flowability. The differences in the levels of gSCC substitution and the V-funnel flow results show general correlations with the increase in GCW. The gSCC prepared by 10 wt% GCW associated with 10 wt% BA and 20 wt% RHA was improved significantly. The filling and passing abilities of the gSCC were improved by using GCW. In addition, gSCC achieved mechanical property development and was able to minimize the consumption of OPC by up to 40%.
