“…In the 60 minutes of the mixing duration, the air content of the mixture containing 50% NP drastically decreased by about 86.7% while the air content of the other four mixtures increased between 17.64 -62.5%. This behaviour of the mixture containing 50% NP might be attributed to the filler effect of finely ground NP which yields a decrease in the air content of the mixture [33]. On the other hand, significant reductions in the air content of the mixtures were observed at mixing times longer than 60 minutes.…”

Ready-mixed concrete suffers in terms of fresh and hardened properties as a result of prolonged mixing, hot weather concreting and/or possible delays in construction site. To overcome these problems, this study focused on the provision of sufficient workability with the retempering of concrete mixtures during prolonged mixing periods with use of superplasticizer (SP). Four mixtures with substitution of different mineral admixtures such as blast furnace slag (BFS), fly ash (FA), ground clay brick (GCB) and natural pozzolan (NP) and control mixture were designed. 5, 60, 120, 180 and 240 minutes mixing periods were applied on the mixtures. 15 ± 2 cm slump value was targeted after the retempering. In addition, air content, 7 and 28 day compressive and splitting tensile strength of the mixtures were tested. Results showed that slump values fall to zero after prolonged mixing when mixtures were not retempered, while slump loss was completely eliminated after retempering with SP. The air content of the mixtures decreased significantly as a result of the stiffening of the concrete after prolonged mixing. After the retempering process, compressive and splitting tensile strengths of the mixtures slightly increased. Also, the fresh and hardened properties of concrete improved with the use of high amounts of mineral admixtures.

“…The density, specific gravity, bulk density, and fineness of agricultural waste ash vary depending on the location and the processing parameters. Figure 9 depicts the specific gravity of agricultural waste ashes such as corncob ash (CCA) [101], SCBA [102][103][104][105][106][107][108][109], groundnut shell ash (GNSA) [89,[110][111][112], RHA [113][114][115][116][117][118], and POFA [119,120]. The chemical composition of the ash is directly related to the interaction percentages of SiO 2 , Al 2 O 3 , Fe 2 O 3 , CaO, MgO, SO 3 , K 2 O, Na 2 O, P 2 O 5 , MnO 2 , and TiO 2 , which are given in Table 9.…”

The rapid urbanization of developed countries and the difficulty in disposing of agricultural wastes have created opportunities for the construction industry to use agricultural wastes. A wide variety of agricultural waste materials are already in use with concrete as substitutes for cement and aggregates, as well as reinforcing materials. This study reviews the available literature published from 1935 to 2022 on agricultural wastes being used as building materials. The research utilizes a bibliographic approach based on the Scopus database. This article retrieves data employing the Scopus database and incorporates 671 articles based on the keywords, agricultural wastes used as building materials. The scientometric analysis is the second step, wherein the patterns of the obtained articles are investigated with various factors such as countries with the most publications, sources that have the most publications, most frequently appearing keywords, and articles with more relevant research works. A summary of the results obtained at various stages of the research is depicted in each phase. Detailed quantitative and qualitative discussions are also conducted to achieve the three main objectives: the summarization of quantitative data, discussion of the existing application, and identification of future research directions. These findings serve the future endeavor of agricultural waste-to-building materials’ incineration academic research. The scientometric review paves the way for academics from various nations to impart novel ideas and information and foster research collaboration.

“…[10], [11]"Bagasse is also used in some countries as a wood replacement in the production of pulp, paper and corrugated board. Bagasse, an agricultural waste from sugar industry, has been found as low-cost metal adsorbent" [12] The Sugarcane bagasse ash (SCBA) is acquired through the control burning of sugarcane bagasse. The SCB creates the environmental nuisance due to direct disposal on the open lands and forms garbage heaps in that area.…”

In today’s regenerating world it is an urgent need for the Disposal of waste material because this waste material is causing pollution as well as problem to humans. Disposal of some waste like metals can be done. But the disposal of waste like ash is only land disposal. which has a limit. This waste can easily be used in the construction industries as the mineral admixture in the concrete, which enhances the mechanical properties of concrete and impacts the physical appearance and chemical properties of the same. This paper deals with the research work done on concrete of grade M40 with the addition of mineral admixtures like eggshell powder and bagasse ash. This research work gives the result that using this item can increase the strength by 13 % in compression and 5% in tension. Using of Glass fiber can increase the tension strength of concrete up to 10% more. The use of this material can reduce the waste and helps to decrease the damage to environment
