“…The maximum strength is around 10% of LP and 10% of GGBFS at early age [3]. The result were determined the compressive strength of the mortar mix of specimens was prepared with the ternary alkali alumino silicate cement 42.4 Mpa at 28 days in increase to 30% compared in Portland cement 32.4 Mpa [2]. In this paper shows about the difference in Split tensile strength between the control mix (15%) 22% reduction compressive strength the compared to the control mix.…”

Cement is the one of the World's most significant manufactured material. 5% of the total release of CO2 to the atmosphere is caused during the manufacturing for cement in cement industries. In an effort to reduce anthropogenic CO2 emission and for the economic reasons by-products are used as cementitious materials. Reuse of a large amount of waste materials like fly ash, PJ ash, silica fume, are done in large extents in the manufacture of cement and cementitious products. Prosopis Juliflora Ash (PJA) is derived from the stem and roots of the PJ tree. In this paper the PJA sample is examined by using FTIR. The peak values from the FTIR test shows the functional groups present in the PJA sample and those functional groups are tabled. In this paper gives the clear view of using stem and roots of the PJ tree and make them as ecofriendly to environment.

“…Sharma et al [10] used a combination of fly ash and slag as stabilizer to modify expansive soil, which showed potential for modification and improvement of soil stabilizers. With the increasing demand for the performance of soil stabilization materials in the fields of engineering application and environmental protection, scholars have made many achievements in exploring the strength improvement of different additives on traditional soil stabilizers [11][12][13][14][15]. Recently, significant achievements had been made in the research on nanoparticle-modified cement, concrete, and other traditional building materials [16][17][18][19][20][21], and positive exploration had also been achieved in the modification of soil stabilizers.…”

A new nano-soil stabilizer (N-MBER, Nanometer Material Becoming Earth into Rock) material was developed in this research by using the high activity and ultrafine properties of nano-SiO2 (NS), which were able to improve the properties of cement-based soil stabilizer and had broad application prospects. The results showed that (1) the strength of N-MBER obeyed a compound function relation with curing period and additive amount of NS. The relationship between strength and curing period obeyed an exponential function when the additive amount was constant. The strength and additive amount were a power function when the curing period was fixed. The compressive strength of N-MBER increased by more than 15% compared with MBER at day 28 of the curing period, and 50% compared with grade 32.5 cement. (2) The pozzolanic catalytic activity of NS significantly increased the amount of calcium silicate hydrate gel (C–S–H) in the N-MBER colloid. NS was also able to make the distribution of the network structure of colloidal space more uniform and improved the fractal dimension of particles by 0.05. The above results provide theoretical data for exploring the mechanism of soil stabilizer strength growth and for promoting the application of solid waste utilization.

“…One such material of burgeoning interest is milled wood waste bottom ash (WWBA), an often-disregarded residue arising from biomass combustion processes. WWBA has gained attention as a supplementary cementitious material due to its latent and pozzolanic hydraulic properties [12,13]. Pozzolanic materials, when finely divided and mixed with Ca(OH) 2 (a by-product of cement hydration), react to form additional cementitious compounds, improving the durability and strength of the concrete.…”

Wood waste bottom ash (WWBA) is a waste generated in power plants during the burning of forest residues to produce energy and heat. In 2019, approximately 19,800 tons of WWBA was generated only in Lithuania. WWBA is rarely recycled or reused and is mostly landfilled, which is both costly for the industry and unsustainable. This study presents a sustainable solution to replace a part of cement with WWBA at 3%, 6%, 9%, and 12% by weight. Problems are also associated with the use of this material, as WWBA could have a relatively large surface area and a high water demand. For the evaluation of the possibilities of WWBA use for cementitious materials, the calorimetry test for the cement paste as well as X-ray diffraction (XRD), thermography (TG, DTG), and porosity (MIP) for hardened cement paste with the results of physical and mechanical properties, and the freeze–thaw resistance of the concrete was measured and compared. It was found that WWBA with a large quantity of CO2 could be used as a microfiller with weak pozzolanic properties in the manufacture of cementitious materials. As a result, concrete containing 6% WWBA used to substitute cement has higher density, compressive strength at 28 days, and ultrasonic pulse velocity values. In terms of durability, it was verified that concrete modified with 3%, 6%, 9%, and 12% WWBA had a freeze–thaw resistance level of F150. The results show that the use of WWBA to replace cement is a valuable sustainable option for the production of conventional concrete and has a positive effect on durability.
