Ceramic materials are largely used in all over the world and consequently, large quantities of wastes are produced simultaneously by tile manufacturers and construction industry. Nevertheless, part of these wastes and those produced by the construction industry are dumped in landfills. This paper presents the effect of using ceramic waste in mortar as cement replacement. Four mortar mixes were prepared in this study and focuses on the effect of ceramic powder as cement replacement on the strength development and the morphology of the mortar. The microstructural characteristics of the mortar were investigated by scanning field emission electron microscopy (FESEM) and the mineralogical properties was investigated using the X-ray diffraction (XRD).  The cement was replaced by ceramic powder from 0% to 60% by weight of cement. The specimens were cast in 50 x 50 x 50 mm cube and water curing regime was used until the age of testing. The fineness of ceramic powder used is less than 45µm. The developments of compressive strength were studied for all samples. It is found that the optimum replacement that gave the highest strength was 40% replacement. It was also found that the use of ceramic powder enhanced the microstructure and strength properties of the mortar.

ABSTRACT Cement is the most consumed building material in the world. However, cement manufacture is responsible for 5–7% of the world CO2 emissions. In this paper, cement was partially replaced by styrene-butadiene rubber (SBR) polymeric latex in order to reduce cement consumption. Besides, effects of SBR addition on the strength and physical properties of plain mortar exposed to three different curing regimes are presented. Three different curing regimes were applied to the 40 × 40 × 160 mm prismatic mortar specimens: (I): Specimens were cured in water until the test age (CW), (II): after demoulding, specimens were immersed in water for 2 days and kept in ambient temperature until the time of the test (2DWA) and (III) involved 2 days of water curing followed by 1 day in an oven at 50°C and subsequentely placing in ambient temperature until the test time (2W1OA). Results showed that combining 2 days of water curing followed by ambient temperature curing (2DWA) along with 3% SBR polymer content showed good performance in terms of compressive strength, water absorption and void content. Moreover, a good performance in terms of flexural strength was observed by combining 2W1OA curing regime with 2% SBR content. However, the detrimental effect of water curing regime (CW) in terms of compressive and flexural strength was also observed with the increase of SBR ratio.

Pozzolanic Properties

Cement is an extremely energy consuming material and its production leads to the emission of a vast amount of greenhouse gases. Cementitious concrete is a universal building material, which is used for the production of various structural elements. The paper describes the problem of cement production and its impact on the environment. This research deals with application of aluminous cement as binder component for the manufacture of refractory composites and with possibilities of further utilization of environmentally friendly materials with pozzolanic properties as a partial replacement of used aluminous cement. These materials are originating as waste in the building industry or by the recycling of cast-off materials. To reduce the costs and adverse effects on the environment was the binder system modified by finely ground ceramic powder and metakaolin. The experimental results present the values of flexural and compressive strength investigated on a series of composite specimens with dimensions of 40×40×160 mm3 and 10, 20 and 30 % of cement replacement. The aim of the present work is to apply the mentioned pozzolanic materials and reach the suitable composite with the sufficient heat resistance and residual mechanical parameters after gradual temperature loading.

Alternative Ingredient

Producing "greener" concrete that meets various construction/industrial needs will have significant positive impacts on both the construction field and the environment. This paper investigates the use of ceramic waste powder (CWP); a waste material from the final polishing process of ceramic tiles, in producing different concrete types; conventional concrete (CV), self-compacting concrete (SCC), and geopolymer concrete. The conducted study highlights the feasibility of using CWP as a cement replacement in producing conventional concrete, as a filler and cement replacement in making SCC, and as a main binder in developing geopolymer concrete. The study signifies the promising opportunities of utilizing CWP as an alternative ingredient in producing green concrete. Different concrete mixtures were prepared and tested for various properties: slump retention for conventional concrete, flowability, passing ability, segregation resistance and viscosity for judging fresh properties of SCC. Strength development for all three concrete types, chloride ion permeability for evaluating the durability characteristics of conventional and SCC, in addition to resistivity test for the produced geopolymer. Results indicated that CWP can be used 10-30% as partial replacement of cement in CV, and 40% in SCC for producing concrete with acceptable fresh and hardened properties. While for the geopolymer a main conclusion was the use of alkali activating solutions with a concentration of 12M to obtain compressive strength for structural applications.

The experimental study evaluated the performance of lightweight aerated concrete incorporating various percentages of palm oil fuel ash (POFA) and pulverized fuel ash (PFA) as partial cement replacement. Performance evaluation of the aerated concrete was investigated with respect to ultimate compressive strength, density and strength development. Twelve mixes are developed and tested at different periods, i.e. 3, 7and 28 days. In this work, two different curing regime namely air curing and water curing were used to monitor the effect of the curing regime. The results show that the mixtures produced by replacing cement with POFA and PFA were comparable to the mix without cement replacement. Furthermore, this investigation observed that the cement-POFA-PFA based lightweight aerated concrete can be produced as lightweight non-load bearing concrete units, because hazard of ashes (POFA & PFA) might be a serious issue for human health. Disposal of ashes contributes the shortage of landfill space in all the worlds, especially in Malaysia.
