mix design,most of the countries have their own specifications.In the present study,standard guidelines of India,Britain and America for the concrete mix design have been discussed.The concrete grades of M25,M35 and M45 were designed and compared.Indian Standards were also compared.It was ...
According to equations (23)–(25), the major mix proportion parameters, including water-to-binder ratio, replacement of fly ash, and GGBFS, can be calculated. The solution procedure can be summarized as follows: (1) Based on the methodology of quantitative durability design for concrete stru...
The study aims at comparing two methods of concrete mix design with angular and rounded coarse aggregate; The Department of Environment Method, UK and The American Concrete Institute Method, using different water to cementitious ratio (w/cm). In this research work 53 grades Ordinary Portland ...
As illustrated in Fig.1, early concrete research has followed three paradigms of science, namely, empiricism, theory, and computation. The properties and performance of concrete can be tailored to meet design requirements by varying the type and quantity of the mixture constituents (e.g., cement,...
design and development of cementitious materials. Existing reviews largely depended on manual appraisals, potentially leading to subjective interpretation. Moreover, there exist many challenges in implementing and interpreting ML models, which have seldom been examined in the literature. In order to tackle...
Table 1 Concrete mix design used for test specimens. Full size table Figure4shows dimensional details of test specimens. The S2 and S2.65 series were 200 mm and 265 mm deep, respectively, and two prestressing tendons with a diameter of 9.5 mm were provided in the compression zone of the ho...
2 Pervious concrete: materials, mix design, and mechanical properties Pervious concrete is a gap-graded material with characteristic pore structure which consists of interconnected, dead end, and capillary pores [21]. The aggregate gradation for the pervious concrete typically consists of single-sized ...
reaction[04]during the curing process, a reaction that supplements and amplifies the primary water-cement hydration reaction. A reaction that is triggered by the introduction of an additional material—a supplementary cementitious material—into the concrete mix design. A pozzolan[05]. The right ...
2.1 Design of Beam Specimens and Program The beam specimens were designed according to (ACI 440.1R-15 2015). The experimental program consisted of nine GFRP-RGPC and three GFRP-ROPC beams with target compressive strengths of 20, 35 and 50 MPa. The beams were divided into four groups, with...
Mix design and preparation of test specimens On the other side, the mix design and preparation depended on the ACI Committee was used to compute the quantities of materials required for the test batch. Many trials mixes were made to adjust the proportions of the used materials to give the 250...
