“…As shown in Figure 11, the final cracking patterns are markedly different for the lower shear strength cases (ST ratio of 1 or 2) as compared to the higher shear strength case (ST ratio of 3). The final damage pattern from the higher shear strength case agrees very well with experimental evidence [35] and the numerical result by other researchers [29]. The next factor examined is the fracture energy ratio between the Mode-II and the Mode-I for the cohesive model, herein referred to as SE ratio.…”

Advanced computational modelling can provide a powerful tool for material investigation and characterisation. For concrete materials, appropriate description of the heterogeneity and realisation of complex fractures are two challenging aspects in high fidelity numerical simulations. This paper presents a new mesoscale model for concrete with the ability of simulating natural evolution of fracture at the interface between the aggregates and mortar matrix and without restriction to the loading conditions. To this end, a combined cohesive and contact interface approach is employed. The contact-friction process at a fractured interface is treated as an independent process that complements the general cohesive law, thus allowing the closure of cracked surfaces and the development of residual shear resistance in a realistic manner. Parametrisation is conducted to examine the effects of pertinent interface parameters on the macroscopic behaviour of concrete. The modelling approach is demonstrated to be capable of simulating the behaviour of concrete under a variety of loading conditions, including confined and dynamic compression. The new mesoscale model provides a comprehensive numerical means for investigating into the micro-mesoscale mechanisms underlying the macroscopic behaviour of concrete.

“…Sieve analysis of powdered form ceramic waste and lime was carried out and result shows that 98.5% of ceramic powder and 58.37% of lime passed through 75µ Sieve as per the Indian codal provision (MORT&H 2012, IS 2386). The chemical properties of the ceramic waste were considered as mentioned [1].…”

“…As reported, Indian ceramics industry, which is comprised of wall and floor tiles, sanitary ware, bricks and roof tiles, refractory materials and ceramic materials for domestic and others use is producing approximately 15 to 30 MT per annum waste. The state of Gujarat accounts for around 70% of total ceramic production in India and out of total production 30% goes as waste and dumped in the open spaces [1]. The advantages of using ceramic waste dust in road construction as mineral filler are: (i) the ceramic dust available at zero economic cost, (ii) chemical and mechanical properties will be consistent, (iii) road construction activity approaches to become green, (iv) durable, hard and highly resistant to biological, chemical and physical degradation forces [2].…”

The purpose of this paper is to evaluate the suitability of ceramic waste as a filler material in Semi-Dense Bituminous Concrete. A bituminous concrete mixes with ceramic dust and hydrated lime were prepared in different proportions (3% and 5%) as filler. The amount of optimum binder content was determined by Marshall Stability test for samples. The mechanical performance was determined for Marshall Stability, deformation behavior or flow, as well as for density and void characteristics base on prevailing Indian standards specifications. Results show that the stability values and other parameters of samples containing ceramic wastes are improved in comparison to conventional mineral filler. The benefits of using ceramic waste in bituminous concrete mixture as mineral filler (3-5%) are therefore recommended. The replacement of conventional filler like lime and other mineral in bituminous concrete by ceramic wastes will have major environmental benefits.

“…In order to use PP as a replacement for cement in concrete, its effect on the properties of cement paste need to be clarified, for example, nucleation or growth-inducing factor of hydrates on their surface in early-age concrete is important because it can affect the properties of late-age concrete. Many relevant studies [4][5][6][7][8][9][10] have been conducted. Tydlitát et al [7] reported that using more than 20% ceramics in blended cement does not affect the compressive strength.…”

“…Tydlitát et al [7] reported that using more than 20% ceramics in blended cement does not affect the compressive strength. In a study performed by Fatima et al [9], concrete was made by replacing up to 30% of the cement with PP resulting in concrete that had good workability, proper compressive strength, split-tensile strength, flexural strength, and elastic modulus. A study by Cheng et al [4] showed that the permeability resistance of concrete mixed with PP is superior to that of a control group, and the most desirable permeability resistance was achieved when the cement substitution rate was 30%.…”

The production of cement leads to a large amount of CO2 emission. Using industrial waste slag, such as ceramic polishing powder (PP), to replace part of Portland cement can reduce the pollution caused by the cement industry and solid waste disposal. In order to use PP as a replacement for cement, its effects on the properties of cement paste need to be clarified. In this study, the effect of PP on the nucleation and growth of hydrates in cement paste at very early ages was investigated. Quartz was used as a reference. The interactions of their surface with various ions in cement paste solution, which has an important effect on the nucleation and growth of hydrates, were studied by using the zeta potential test. The morphology of the nucleus and crystal of hydrates was investigated by using SEM. The zeta potential measurements showed that the affinity of the surface of PP and quartz to ions in the pore solution of cement paste is similar. The image of SEM indicated that there is also not much difference in the crystallization of hydrates on the surfaces of PP and quartz. These evidences suggested that PP has similar surface charge properties as quartz, and its effects on the properties of cement paste are the same as that of quartz. From the viewpoint of the effect on very early hydration, PP can be used in cement paste, similar to quartz power.
