“…Use of burnt stone slurry (BSS) waste by replacement with silica in concrete mixtures was investigated and found that in case of mortar, workability decreased with increment of BSS content due to the low rate of reaction of the BSS compared to that of cement [22].Also, the utility of quarry dust limestone powder (QLP) in self-compacting paste and concrete applications was investigated and it was concluded that the incorporation of QLP increased the viscosity of the cement paste at the same water/powder ratio and superplastizer dosage [23].…”

The utilisation of stone waste, in the form of mineral admixture as a pozzolanic and non-pozzolanic material for mortar and concrete has received considerable attention in recent years. This interest is part of the widely spread attention directed towards the utilisation of wastes and industrial by-products in order to minimise Portland cement (PC) and sand consumption, the utilisationof which being environmentally damaging. Another reason is that mortar and concrete, which contain pozzolanic as well as non-pozzolanic materials, exhibit considerable enhancement in durability properties. This paper reviews work carried out on the use of stone waste as a partial non-pozzolanic replacement for sand in mortar and concrete and in the containment of hazardous wastes. The literature demonstrates that different stone wastes is an effective inert filler which causes great improvement in the pore structure and hence the resistance of the concrete to the action of harmful solutions.

RESUMONeste trabalho é avaliado o processo de corrosão das armaduras induzido pela ação de íons cloreto em concretos produzidos com adição do Resíduo do Beneficiamento de Rochas Ornamentais (RBRO). No estudo de caracterização, foram avaliadas propriedades físicas, químicas e mineralógicas do RBRO. Foram produzidos concretos com três níveis de relação água/cimento -0,45; 0,55 e 0,65 -e quatro níveis de adição de RBRO -0, 5, 10 e 15%-em relação à massa de cimento. No estado fresco foi avaliada a propriedade de consistência do concreto; no estado endurecido foi avaliada a resistência à compressão axial; as propriedades relacionadas com a durabilidade estudadas foram absorção de água por imersão e fervura, absorção por capilaridade, além de ciclos semanais de indução e aceleração da corrosão por ataque de cloretos e monitoramento do potencial de corrosão. Por último, foi feito o ensaio colorimétrico por aspersão do indicador AgNO 3 a 0,1 mol/L. Os resultados mostraram que a adição de RBRO é vantajosa no teor de 5% de RBRO do ponto de vista da resistência mecânica e de durabilidade frente à ação de cloretos. Palavras-chave: durabilidade de concreto armado; corrosão eletroquímica; potencial de corrosão; método colorimétrico; Resíduo do Beneficiamento de Rochas Ornamentais (RBRO). ABSTRACTThis research evaluates the reinforcement steel corrosion process induced by chloride ions in concrete containing ornamental rock waste (ORW) as mineral addition. Physical, chemical, mineralogical analysis and particle size distribution of ORW were performed. Concrete mixtures were produced with three levels of water / cement ratio -0.45; 0.55 and 0.65 -and four levels of ORW addition -0, 5, 10 and 15% -by weight of the binder. Consistency of fresh concrete and compressive strength of hardened concrete were evaluated; water absorption and capillary absorption of concrete were performed as durability features. The concrete specimens were exposed to wet and dry cycles and corrosion potential monitoring test. Finally, the colorimetric method (AgNO 3 of 0,1 mol/L) was performed. Results show that the 5% ORW content ratio is beneficial to concrete at mechanical and durability perspectives against chloride ion attack.

“…In the construction of engineering structures such as highway embankments or earth dams, loose fills are required to be compacted to increase the soil density and improve their strength characteristics [1]. Sometimes, an existing soil deposit may need to be improve in order to enhance its engineering performance [2] Compaction is the most common and important method of soil improvement.…”

The aim of this research is to study the effect of using (Al-KHAMKHA) is stone cutting slurry waste local name in JORDAN on the unit weight and moisture content of Jerash cohesive soil Al-Khamkha which is the local name of the stone cutting slurry waste which is produced during the cutting operation, This water carries large amounts of stone powder, which leads to complex nature of environmental problem so these waste material needs to be utilized meaningfully in economic way. The degree of compaction of a soil is measured in terms of its dry unit weight Al-Khamkha mixed with Jerash cohesive soil at different amount ranges from 0%, 5%, 10%, 15%, up to 50% and compaction characteristics of Jerash cohesive soil without and with different amount of Al-Khamkha was studied. This investigation show that as the amount of Al-Khamkha increase from 0% to 15%, the dry unit weight of Jerash cohesive soil increase from 14.4 KN/m 3 at 0% of Al-Khamkha to 16.5 KN/m 3 at 15% and after that .any increase of Al-Khamkha decrease the dry unit weight. On the other hand, the optimum water content of the Jerash cohesive soil was increases with increasing the percentage of Al-Khamkha on the cohesive soil.
