Keywords: ecoconstruction blocks, marble sludge powder, cement, 1 Introduction Nowadays, the growing consumption of available natural resources as raw materials in industry leads to their decreasing quantity, as well as quality, in nature. In addition, the marble cutting industry generates a high volume of wastes.
Aug 10, 2019· Free Powerpoint Templates Page 10 Raw materials and test methods Cement : Ordinary Portland Cement (43 Grade) with 28 percent normal consistency with specific surface 3300 cm2/g conforming to IS: [8] was used. Marble sludge powder : Marble sludge powder was obtained in wet form directly taken from deposits of marble factories.
EcoFriendly Concrete is a concept of thoughtful environs into concrete considering every aspect from raw materials ... Through reaction with the concrete admixture, Marble sludge powder and ...
Therefore, there are sludge pools with high and low titer content on cement plants. The sludge from pools is mixed in certain proportions. In this connection, each cement plant has its own, unique composition of raw materials for production of finished goods. For example, a mixture of materials used by some cement plants in Ukraine.
Mar 01, 2020· The feasibility of using raw sludge as a water replacement in cementbased materials was investigated by Hamood et al. (2017) who collected raw sewage sludge from a STP containing % liquid, which was mixed with unprocessed fly ash with high carbon content and large particle size to replace cement with various proportions. Contrast with the ...
Utilization of waste industrial sludge as a raw material to reduce their adverse effect on environment and make it ecofriendly. Marble sludge powder can be used as filler and helps to reduce the total voids content in concrete. This paper presents the feasibility of the usage of marble sludge dust hundred percent substitutes for natural sand in concrete.
The concrete industry is among the largest consumer of raw materials. Limestone fillers are generally used in concrete. As marble stone is of limestone origin marble is formed by metamorphism of limestone. The effect of addition of nonpozzolans powder waste from marble industry is studied for its suitability in SCC.
Raw material characterization Chemical analysis (XRF) Table 2 shows the chemical analyses of the raw materials as obtained from XRF analyses, whereas Table 3 presents the percent of free silica and organic matter of the two wastes. The loss on ignition obtained is significantly higher in case of marble waste than that of granite waste.
Based on properties of raw materials, two different mix proportions are taken and given in Table 4. Mix A is the controlled concrete using river sand and Mix B is the green concrete using Industrial waste (50% quarry rock dust and 50% marble sludge powder) as fine aggregate. The water/cement ratio for both the mixes was % by weight.
This powder flows along with the water as marble slurry or marble sludge. The marble slurry has nearly 35%45% water content. This work aims at studying the recycling potential of a nontoxic sludge generated from natural marble manufacturing processes in the preparation of innovative concrete as building material with regards to
Jun 01, 2011· Moreover, the marble sludge as raw cement material lowered the pouring temperature of the clinkers in the sintering process. The melting of the ECI and ECII clinkers was distinctly observed and also prevented C 2 S from transferring into C 3 S, resulting in only a small amount of C 3 S content being discovered in the ECI and ECII clinkers.
Aug 01, 2016· marble sludge powder as raw materials ", WIT Transactions on Ecology and the Environment sustainability, environment, waste reuse 2009, Vol .
using marbel sludge as cement raw material vivifucecchioit. Comprehensive literature review on use of waste replacement The raw materials, used for this study are natural coarse aggregate, fine aggregate, Sheet glass Powder (sewage sludge), Project on Partial Replacement of Cement with Dust and Marble Sludge powder as a fine aggregate ARPN J.
Raw materials used for manufacturing of Portland cement are found naturally in the earth''s crust. It is made primarily from calcareous and argillaceous materials and gypsum. Calcareous materials contain limestone or chalk while argillaceous materials comprise an oxide of silicaalumina and iron. Both are found as clay or shale.
Jun 15, 2016· The influences of the cement raw mix composition and the different burning temperature were investigated to evaluate the reuse feasibility of marble sludge waste material in cement production. Calcium sulfoaluminate–belite cement, environmentally cement, can be produced by raw mix contains in weight percent 25% kaolin, 20% gypsum and 55% ...
To account for inorganic ashes that would remain from sewage sludge after burning, it was found that up to 14% of the raw materials used in cement manufacture could be replaced with sewage sludge ...
Incorporation of GP in mortar and concrete in ratios of 10, 20, 30 wt.% improved mortar and concrete compressive strengths and the concrete workability. The experimental results show that GP can be used to replace cement or fine aggregate in concrete which provide not only solve an environmental problem by safe disposal of GP but also reduce ...
usable as a cement raw material, which dries up the sludge with heat generated by the following hydration reaction. CaO + H2O → Ca(OH)2 + kcal/mol The product, called dried powder sludge, is sterilized, very low in moisture content and odorless. It can then be utilized as a raw material of Portland cement and fuel at the same time.
sludge replaced part of marble material, it still succeeded in making cement. However, there are three reasons reduced the marble waste sludge as raw materials for cement. First, Cement yield in Taiwan was reducing. Second, using marble waste sludge in manufacturing of cement affected its quality. Last, lowcarbon policy is pursuing.
Lime sludge (chalk) obtained from fertilizer industry has been tried as the constituent of masonry cement, burning of lime sludge to make building lime, as raw material for making flooring tiles and compounding of burnt lime waste with surkhi/fly ash to make limepozzolana mixtures / composite mortars.
Ceramic industry is capable of incorporating and reusing different types of industrial waste materials. Recently, the reuse of ornamental stone cutting sludge slime in this industry is becoming a common practice. This work investigates the changes in the physical and mechanical properties of the produced ceramic tiles from raw materials containing marble sludge slime produced in the ornamental ...
Jul 09, 2014· The paper industry that uses recycled paper as raw materials has as byproduct paper sludge, which has a high content of calcium carbonate, organic materials and other minerals. Because its pozzolanic activity, the paper sludge can be used as cementitious materials in building industry.
Lime sludge (chalk) obtained from fertilizer industry has been tried as the constituent of masonry cement, burning of lime sludge to make building lime, as raw material for making flooring tiles and compounding of burnt lime waste with surkhi/fly ash to make limepozzolana mixtures / .
