Use of Waste Ceramic as Aggregate in Concrete

This research paper represents the experimental study on use of ceramic waste material as an aggregate in concrete. To reach the goal of sustainable development utilization of waste materials in concrete production is very much useful. The ceramic aggregate used in this study was recycled from industrial ceramic tile waste in India. From the results it can be seen that it is possible to produce a concrete with good strength by using ceramic waste as an aggregate in .It is also seen from the results that the compressive strength characteristics of ceramic aggregate concrete met the required criteria set by various international standards and codes, which shows the ability of ceramic waste to be used as a substitute to the conventional aggregates in concrete. We replaced the coarse aggregate in concrete by 100% to thewaste ceramic aggregate of size 10mm. The water cementratio taken was 0.30 for concrete production and compared it with normal aggregate concrete of M20 grade. By the decrease in water/cement ratio, high strength concrete canbe obtained. But it is found that the workability will be very low. In our project the required workability was achieved by the use of maximum water-cement ratio .To overcome this use of several admixtures like super-plasticizers and silica fume are recommended to add in the mixing so that the workability can be improved.

Analysis of Measured Parameters in Relation to the Amount of Fibre in Lightweight Red Ceramic Waste Aggregate Concrete

The present study provides a correlation and regression analysis of lightweight waste aggregate concretes with varying degrees of fibre reinforcement. The concrete mix contains pre-soaked red ceramic waste aggregate, expanded clay coarse aggregate and Portland cement. Copper-coated crimped steel fibre was used as the reinforcement. The experimental results included properties measured by destructive test methods—compressive strength, splitting tensile strength, static modulus of elasticity, the limit of proportionality, shear strength; and by non-destructive test methods—dynamic modulus of elasticity and surface electrical resistivity. These properties were analysed to study the relevancy and significance between non-destructive and destructive methods of measurement in the case of different amounts of fibre. The results show differences in the degree of fit to the linear and quadratic regression curves for pairs of destructive and non-destructive test results. As expected, the linear relationship can be applied in a few cases, but the quadratic curve must be used for a few pairs. Another observation is that it is not possible to neglect the amount of fibre in the correlation analyses of the measured properties.

Improving Sustainability of Technical Ceramics Production: Synergistic Approach

Sustainable development is a concept focused on preserving current resources for them to be available to future generations as well, while at the same time fulfilling current human needs and facilitating adequate levels of development. Nowadays, there are many possible applications of sustainability principles, such as in the fields of the economy, agriculture, environment, energy, transport, architecture, and production. Sustainable production of materials and goods aims at improving the processes which are less damaging to the environment, which conserve natural resources and use low levels of energy, possibly derived from sustainable sources. One of the intensive energy- and resource-consuming industries is the conventional production of technical ceramics. Although non-toxic, ceramic waste is generated during the machining of the green bodies and is typically landfilled. To improve the sustainability of technical ceramics production, methods of recycling ceramic waste need to be developed and applied.

Study the Effect of Using Ceramic Waste Powder as Partial Replacement for Cement on Concrete Properties

Ceramic waste is one of the most active research areas that encompass a number of disciplines including civil engineering and construction materials. Ceramic waste powder is settled by sedimentation and then dumped away which leads to environmental pollution, in addition to forming dust in summer and threatening both agriculture and public health. Therefore, utilization of the ceramic waste powder in various industrial sectors especially the construction, agriculture, glass and paper industries would help to protect the environment. It is most essential to develop eco-friendly concrete from ceramic waste. In this research replacing the (OPC) cement by ceramic waste powder has been studied accordingly in the range of (0, 10, 15, and 20) % by weight of M-30 grade concrete. Concrete mixtures were produced, tested and compared in terms of compressive and tensile strength to the conventional mixture. These tests were carried out to evaluate the mechanical properties for 7 and 28 days. As a result, the CWP cement concretes decreased the workability retention. The values of average hardened concrete density for concrete mixes with CWP cement are higher than the reference mix in 7 days, but lower than the reference mix in 28 days. The maximum value of compressive strengths at 7 and 28 days and tensile strength was achieved at about 5% CWP concrete mix. CWP slowed the compressive strength development especially at early ages. All mixtures with CWP showed good strength development at 28 days. It was observed that all CWP replacement ratios achieved higher compressive strength than characteristic compressive strength which is equal to 30 N/mm2 in 28 days, except the 20% ratio gives 29.72 N/mm2. Test results showed that CWP has potential to be used as an ingredient in concrete mixtures to partially replacing cement. The study showed that concrete mixtures with ceramic waste powder (CWP) had variable performance of the measured properties depending on the replacement level used.
