“…This result is fully agree with that of P. Dabic et al (2006) [6]. The limestone filler, which has been considered by several researchers as an inert material, is gradually accepted as contributing to the hydration process by the formation of hydrated calcium monocarboaluminates [7].…”

Abstract. In the present study, the hydration of Portland cement pastes containing 5%, 10%, 15% and 20% tuff, limestone filler and granodiorite was investigated by thermogravimetric analysis coupled with differential scanning calorimetry and microcalorimetry isotherm. The monitoring of the hydration kinetics by thermogravimetric analysis made it possible to quantify the quantity of water combined with the cement (nonevaporable water) and the degree of hydration. By coupling this technique to the differential scanning calorimetry, it was also possible to measure the energy absorbed or released by the material during its decomposition. The results showed that the non-evaporable water content and the degree of hydration of the mixtures containing various mineral admixtures were relatively lower with respect to the reference mixture when as the content of mineral admixture increased. The effect of the evolution of the hydration process on the mechanical properties of mortars was also monitored. The relative variation of the compressive strength to that of the flexural strength was evaluated at 7, 28 and 90 days. Results showed that all the mixtures have a greater contribution in flexion than in compression.

“…This confirms the findings of Raimondo, Dondi, Gardini, Guarini, & Mazzanti (2009) that stated that the ability of brick to absorb water is dependent on its microstructural characteristics, especially amount, size and shape of pores. According to Lewis, Sear, Wainwright, & Ryle (2003), fineness of particles affects the water required for concrete workability. This can be implemented to the bricks with the finer particles; it will reduce water necessity in the mix.…”

“…It should be noted that all B10 concrete of steel potential was significantly below the threshold value stated by ASTM C876, Table 9. This pozzolanic reaction reduces the porosity and permeability of cement paste making it stronger and significantly more durable [23]. Use of superplasticizer in concrete lead to reduced water content and further to low permeability, thereby, reducing the penetrability of the aggressive ions.…”

Recycling of construction and demolition waste and recycling of industrial by-products into building materials has an enormous potential. Brick waste can be treated by reusing for construction. Recently, the utilization of pozzolanic materials in cement and concrete have increased considerably due to their diverse benefits such as lesser use of cement , saving in production costs, improvement in the durability of concrete and so on. Ground bricks was added to concrete mix as partial replacement of cement at (5, 10, 15) % by weight. It was evaluated as a pozzolanic material in conjunction with high range water reducing admixture superplasticizer (HRWR)-The study confirmed that the use of 10 % of ground brick improved compressive, flexure strength of concrete by about (23.3%) and (5.92%) respectively at 240 days as compared to reference concrete and decreased the depth of water penetration under pressure by about 43.75% at 150 days, also the water absorption decreased by about 2.52%. The uses of 10% of grinding brick in conjunction with high range water reducing admixture reduced corrosion of steel reinforcement by about 18%.
