“…For example, some ashes derived from agricultural biomass, such as rice husk, biochar, and pam oil fuel ash, have been successfully used in cement or concrete as supplementary cementitious materials (SCMs). It is well-known that the use of rice husk ash in a concrete matrix can improve the strength and durability of concrete due to the pozzolanic reaction between highly reactive amorphous silica from rice husk ash and portlandite from cement hydration [8][9][10][11][12]. Cuthbertson et al [13] used biochar from residual biomass of the bio-ethanol industry as a concrete filler.…”

Due to the increased demands of adapting the sustainability concept in the construction industry, many researchers have developed and evaluated the composite materials made with agricultural by-products, such as straws, fruit-shells, and cobs, as construction materials. Because no research work has been reported regarding the incorporation of common reed fiber (CRF) into a concrete composite to produce the green and sustainable concrete, this research has focused on the evaluation of physical, mechanical, and thermal properties of mortar mixture containing CRF regarding density, porosity, compressive and flexural strengths, and thermal conductivity. In total, six mixtures with 0%, 2%, 4%, and 6% CRF; 0.5% steel fiber (SF); and the combination of 6% CRF and 0.5% SF were prepared. Based on the experimental outputs, a simple analysis of heat loss was also been performed. The test results presented that the incorporation of CRF into mortar mixture proportionally reduced its unit weight and significantly increased its absorption capacity and porosity. Although the use of only CRF in the mortar mixture did not improve both compressive and flexural strengths compared to the plain mixture, the combined use of CRF and SF to increase both compressive and flexural strengths generated a synergetic effect to increase both strengths. The addition of CRF to the mixture has the benefit of producing a significant decrease in heat loss for a typical building in Astana due to the lower thermal conductivity and higher porosity to density ratio.

“…e use of ashes by the grinding process in cement concrete generally improves the properties of concrete. e concretes containing ground fly ash or RHA are of good quality with reduced porosity and improved resistance to sulphate attack and chloride penetration [4,5] as well as high strength [6][7][8]. Comparing to the fly ash which is the most common pozzolan being used worldwide in soil stabilization [9], the utilization of rice husk ash as pozzolanic material is still comparatively low.…”

e potential and efficiency of using rice husk ash (RHA) to add up or partially replace Portland cement in deep cement mixing technique are examined. A series of unconfined compression tests on cement-RHA-stabilized clay are conducted to investigate the influence of RHA on the mixture properties. Special attention is paid to its efficiency for increasing the strength by partial cement replacement to obtain high-strength soil cement, and it is compared with fly ash. Test results indicate that up to 35% of RHA could be advantageously added up to enhance the strength if the cement content in the mixture is larger than 10%. e RHA enhances the strength of cement-admixed clay by larger than 100% at 28 days. For curing time of 14 and 28 days, the RHA exhibits higher efficiency on Portland cement replacement when the cement and overall cementitious contents are not less than 20 and 35%, respectively. e optimum condition for high-strength mixture is achieved when RHA is added to the 20% cement content mixture. When compared with fly ash of similar grain size, the efficiency of RHA is higher when the content to be added is greater than 15%. is indicates the suitability of RHA for use in high-strength soil-cement.

“…Case 1: Constraints of a five (5) component experimental mixture for concrete production: the multicomponent constraints in Eqns. 9-14 have been developed from concrete production literature references and end conditions from earlier research results on the utilization of additives as partial replacement for ordinary cement or as an enhancer of concrete mixes in concrete production [10][11][12][13][14][15][16][17]. Under the conditions of an additive serving as partial replacement for cement with cementing or pozzolanic properties, it is considered a minor component in a mixture of mixture experiment (MME).…”

Extreme vertex design (EVD) has been adapted to be used in the modeling of the behavior of mixture experiments in civil engineering. This method has been in use since the 1970s and has be prevalent in the field of medical science. Various other methods of design of experiments have been used in engineering but neither has EVD being used particularly in civil engineering. This review is presented to serve as a hub or guide for subsequent exercise where concrete production, asphalt production or modification, soils stabilization and concrete improvement or water treatment would be studied with the help EVD. Its ability to fix design points and centroids has been reviewed in this work. EVD operates with various algorithms and depends on the order or condition of problems to be solved. The XVERT algorithm working on Minitab and Design Expert platform was adopted in this review work because of its efficiency in handling quadratic model problems like the four cases reviewed in the present work. From the four special cases, it can be asserted that there is a confidence in the use of EVD to develop the constraints, design the experimental factor space, design the mix proportions, and validate the models resulting from these procedures after experimental specimens are tested to determine the responses.
