“…By comparison, the highest peak of pores, portlandite and partially hydrated cement grains, and lowest peak of hydration products are appeared in the ACM containing WMD, except the portlandite peak of ACM containing 15% of WMD is the lowest. In addition, there is no visible WMD peak apparently due to two reasons, the WMD is mixed and adherent with the partially hydrated cement grains and the calcite provided by WMD reacted with tricalcium aluminate which led to the formation of calcium carbo-aluminates [1,22,40]; however, the peak of hydration products appeared lower in the ACM containing WMD. This is due to a decrease of C-S-H content, this content representing between 50%-70% of the hydrated products.…”

“…As can be seen from the mortars containing WMD, the WMD does not appear in the images and the ettringite is too big compared to that of control mortar. This is could be explained by the reaction of calcite provided by WMD with tricalcium aluminate, which led to the formation of calcium carbo-aluminates [1,21,40]. This new chemical element is introduced in the formation of Ettringite that is why the WMD does not appear in the images and the ettringite is too big.…”

“…The leading factor influencing the quality of cement-based composites and their appropriate adherence is ordinary Portland cement. The manufacturing of ordinary Portland cement requires a meaningful consumption of energy [1,2] and the production of enormous greenhouse gas emissions, including carbon monoxide (CO), carbon dioxide (CO 2 ), nitrogen oxides (NOx), black carbon (BC), and sulfur dioxide (SO 2 ) [3], therefore contributing to environmental pollution [4,5]. Global cement production (4.18 billion tones in 2014) is the third biggest source of carbon dioxide emissions [6].…”

The aim of this study is to assess the possibility of utilizing waste marble dust (WMD) as a partial cement substitution in air-cured mortar (ACM). Three different levels of cement replacement were analyzed: 5%, 10% and 15% by cement weight. The specimens were manufactured in a local laboratory at an air temperature of 22 ± 2 °C and a humidity equal to 20 ± 1%. The chemical and physical properties of ordinary Portland cement and WMD has been found to be the most crucial parameters. A variety of macroscopic tests, such as apparent density, porosity and compressive strength, were proposed in order to explain the effect of utilizing the WMD on the ACM. To confirm the results of the macroscopic properties, thorough microstructural analysis using scanning electron microscopy (SEM) was performed. The obtained results of this study indicate that replacing cement with WMD affects the physical and mechanical properties of air-cured mortar. The apparent density and compressive strength decrease while the porosity increases.

 Abstract: The study focused on the effect of marble dust 0-10% (MD) by weight of cement content, waste foundry sand 0-30% (WFS) replaced by normal river sand and inclusion of glued steel fibres 0-1.5% (GSF) by volume fraction and also 1.5% of chemical admixture(SP) by weight of binding materials produced the excellent quality of structural concrete. Conversely, the replacement level of WSF can be limited up to 30%, Further, add into the concrete will affect the strength. From the test results observed that the 10% of MP, 20 % of WFS with 1.5% of GSF along with 1.5% of SP in concrete produced the higher compressive strength was 34.20, 39.90 and 42.50 N/mm 2 at 7, 28 and 56 days respectively, the strength was increased up to 7.40% than compared to controlled concrete. Also, a higher amount of bending stress was measured from 3.30 to 4 .57 MPa at 28 days for various mixes of concrete and the ultrasonic pulse velocity values are recorded between 3630 to 4030 m/sec for various mixes at 28 days. Finally, the durability measurement of RCPT and also material characteristics test on the modulus of elasticity of concrete were studied systematically.

“…The increase in industrialization and urbanization rates due to economic and population growth has turned construction industry into one that consumes the most of natural resources and generates solid waste that negatively impacts the environment [3]. It is justified to affirm that the use of recycled aggregate is a way to reduce the impact concrete production may cause to the environment [4,5]. Incorporating the maximum possible amount of recycled material in concrete would contribute to the reduction of greenhouse gases emission as well as to minimize the amount of energy spent in concrete production.…”

Fine-grained cement-based composites used in civil engineering and construction industry are usually made of cement-based matrix and natural aggregate (such as sand, gravel, crushed stone, etc.). Red ceramic waste aggregate is considered as a perspective replacement of a part of natural aggregate in modern environmentally oriented building materials. Fine-grained cement composite with natural aggregate partially replaced by ceramic waste aggregate usually show different mechanical fracture characteristics from ordinary fine-grained concrete. The specimens were tested at six different ages. This was the reason for conducting the research programme. Altogether, 6 fine-grained cement mixtures with various proportions of natural and red ceramic waste aggregate were prepared. The aim of this paper is to present and compare mechanical fracture properties obtained from static and fatigue tests. Bulk density, flexural and compressive cube strength, fracture toughness and fatigue properties (S−N − Wöhler curve) were of special interest. All of these tests are important for a practical application of concrete with ceramic aggregate for structures. All the results were statistically analysed and they showed that the fatigue and mechanical fracture properties were improved or at least kept up with the increasing levels of red ceramic waste aggregate. Environmental impact of application in construction industry of composites in question is discussed.
