Due to the increasing need for sustainability, the need for a cleaner environment and resources conservation has now become very important. This study investigates the possible utilization of waste glass powder combined with pulverized fired clay brick wastes as a partial replacement for Portland cement in the production of mortar. The fired clay bricks and glasses were sourced as waste materials and then crushed into powder form. It is then combined and used to partially substitute Portland cement in the mortar at replacement levels of 0, 5, 10, 20, 25, 30, 40 and 50% using a mix ratio of 1:2.75 at 0.5 water-binder ratios. Physical, chemical and morphological characterization was carried out on the pulverized materials. Further, the compressive strength test was carried out on casted 100 mm cube samples after curing by immersion in water. Obtained results revealed the pozzolanic reactivity potential of the blended waste glass and fired clay brick powder due to their amorphousness and high silica content, while also exhibiting similar oxides compositions. Moreover, the obtained compressive strength results of the blended mortar depict improved strength especially at an optimum value of 15% cement substitute with the blended fired clay brick and glass powder compare to the control. It is therefore suggested that blended mix of waste glass and fired clay brick powder with cement can be used in mortar component instead of open disposal in a landfill.

This paper studied the mechanical properties of concrete with cement partially replaced by recycled clay-brick-powder. Four variables (water/cement ratio, sand ratio, replacement level and average particle size of clay-brick-powder) were considered. Each variable had four levels. By using the orthogonal experimental design method, total 17 mixes, including one normal cement concrete as reference, were tested. Experiment results showed that recycled clay-brick-powder could be used as partial replacement of cement in concrete without reducing its properties. The strength was not significantly reduced with cement replacement level up to 25%. The elastic modulus was lower compared with cement concrete.

Background: Investigations on the use of waste clay brick powder in concrete have been extensively conducted, but the analysis of waste clay brick powder effects on cement paste is limited. Materials and Methods: This paper discusses the effects of waste clay brick powder on cement paste. Fragmented clay bricks were grounded in the laboratory using a ball mill and incorporated into cementitious mixes as partial replacement of Ordinary Portland Cement. Workability, consistency, setting time, density and compressive strength properties of paste mixes were investigated to better understand the impact of waste clay brick powder on the cementitious paste. Four cement replacement levels of 2.5%, 5%, 7.5% and 10% were evaluated in comparison with the control paste. The chemical and mineral compositions were evaluated using X-Ray Fluorescence and X-Ray Diffractometer, respectively. The morphology of cement and waste clay brick powder was examined using a scanning electron microscope. Results: The investigation of workability exhibited a reduction of slump attributed to the significant addition of waste clay brick powder into the cementitious mixes, and it was concluded that waste clay brick powder did not significantly influence the density of the mixes. In comparison with the control paste, increased values of consistency and setting time of cement paste containing waste clay brick powder confirmed the information available in the literature. Conclusion: Although waste clay brick powder decreased the compressive strength of cement paste, 5% partial cement replacement with waste clay brick powder was established as an optimum percentage for specimens containing waste clay brick powder following curing periods of 7 and 28 days. Findings of chemical composition, mineral composition and scanning electron microscopy of waste clay brick powder demonstrated that when finely ground, fragmented clay bricks can be used in concrete as a pozzolanic material.

A possible use of waste ceramic powder as a partial replacement of Portland cement in blended binders is studied. For the ceramic powder, originating from the contemporary hollow bricks production, the measurement of chemical composition is done using XRF and XRD analysis. The particle size distribution of ceramics and cement is accessed on the laser diffraction principle. The blended binders containing ceramic powder in an amount of 8, 16, 24, 32, and 40% of mass of cement are used for the preparation of cement pastes which are then characterized using the measurement of basic physical properties and mechanical properties. Experimental results show that an application of 16% waste ceramics in the blended binder provides sufficient mechanical properties of the paste. This makes good prerequisites for future research that will be focused on the development of new types of cement-based composites with incorporated ceramic waste powder.

This research determined the proper gradation of clay brick powder, PET to clay brick powder ratio, and curing temperature. Density, compressive, and tensile strength of the PET-Brick Powder Mixture were also studied. The research results indicate that the mixture had lower density and water absorption. The strength increased quickly and reached the 94% of 28-day strength at 6 hours. The proper initial curing temperature is 180°C.

Compressive Strength Development

Nowadays geopolymer concretes are subjected to heat curing. A large amount of highly corrosive and the hygroscopic alkaline activators are nowadays generally utilized in producing geopolymer concretes. In this paper, hybrid Ordinary Portland Cement (OPC) and geopolymer mixes are developed. The mainly used activator id the Solid potassium carbonate at different percentage is used as 5% & 10% of the weight of geopolymeric materials and OPC was blended with geopolymeric materials in different proportions. By adding cement, improves all the geopolymer properties except workability. By Applying external heat, it plays an important role in gaining strength. Strength gained by the absence of external heat is achieved by using Portland cement as a partial replacement of geocement. The influence of OPC content on the compressive strength development is investigated, and the optimized amount of solid activator to be used in the mix is also investigated. It is observed that percentage of strength increase decreases from52.24% to 14.77% as the OPC content increased from 20% to 60%.

This study examined the effect of curing medium on the strength characteristics of concrete made with magnetic field treated water (MFTW) and clay brick powder (CBP) in partial replacement. Clay brick powder as part replacement of cement at 10, 20, 30 and 40% and MFTW was used to prepare concrete cubes which was cured for 7, 14, 28 and 56 days. Three curing environments used were seawater, acidic water (HCL) and magnetized water. It was observed that the slump test on fresh concrete indicates good workability for MFTW and higher compressive strength than others cured in seawater and HCL condition. Concrete made with 10% CBP using magnetized water and cured in seawater have the highest strength at 56 days. The implication is that construction of bridges and other marine structures may consider the use of MFTW as mixing water to ensure strength development and enhance design life of concrete members.

This paper investigated the effect of clay brick powder (BP) on expansion behaviors of mortar bars using rhyolite aggregates, local volcanic rock from central Thailand. The accelerated test condition (ASTM C 1260) was used in this study. The expansion of samples with varying percentages of BP as cement replacement were compared to those of cement mortar bars. The brick powder significantly reduced expansion of mortar bars. As the percent replacement increased, the larger percentage of expansion reduction was. Due to the possible negative effects on mechanical properties of the mixture, the amount of the supplementary materials should be kept as low as possible. The mixture with 30% BP which yielded expansion below 0.05% at 14 days after acceleration, was chosen to study the effect on strength reduction, compared to the plain mixtures under normal and accelerated conditions. Compressive strength of BP samples under accelerated condition was slightly lower (approx.4%) than that of under normal curing while the strength of control mix was significant lower (of 18%) under similar conditions.
