“…One example is the granite dusts described in [75], which greatly increase the amount of water required to make the concrete mix workable. Similar observations are described for concretes containing glass powder [76], marble powder [77,78], quartz powder, dolomitic powder and other stone dusts [79] and sewage sludge waste [80]. Studies described by other researchers confirm that it is possible to shape the consistency of a dust-containing mixes freely with the superplasticizers [75].…”

Sand has been considered to be something of an immeasurable quantity. There are many indications that this view is no longer valid and that the limiting of natural aggregates usage is doubly justified. Firstly, the extraction of natural aggregates is expensive and has a huge impact on the environment. The main issues in sand and gravel mining are the large areas that are affected, ground water level changes, illegal mining, unsuitability of desert and marine sand, and costs of transport. Secondly, metallurgical waste can be used as a substitute for natural aggregates. This is doubly beneficial—the waste is recycled and the use of natural aggregates is reduced. Waste is stored in landfills that take up large areas and there is also the possibility of ground and groundwater pollution by hazardous compounds. The research presented in this article focuses on the technological conditions of using metallurgical waste in its original form and as a component of recycled concrete aggregate (RCA). The use of metallurgical sludge waste or crushed or round RCA to produce concrete deteriorates the consistency and does not significantly affect the air content and density of the concrete mix. RCA lowers the density of hardened concrete. Metallurgical sludge waste or RCA usage adversely affect the absorbability and permeability of concrete. Concrete containing metallurgical sludge waste is of higher compressive strength after 7 and 28 days, with up to 60% of waste as a sand replacement. RCA concrete achieved higher compressive strength also.

“…However, it was clearly proved that the additional C-S-H gel formation during the hydration of setting properties, which react the bonding/binding the cement with foundry sand. [17][18][19][20][21] concluded that the experimental test results produced the good strength improvement and also long term performace in durability studies showed a less chloride ion penetration of low permeability of averaged coulombs was noted 750 coulombs at 90-days and 365-days 500 coulombs in accordance with ASTM C1202-97.…”

 Abstract: The study focused on the effect of marble dust 0-10% (MD) by weight of cement content, waste foundry sand 0-30% (WFS) replaced by normal river sand and inclusion of glued steel fibres 0-1.5% (GSF) by volume fraction and also 1.5% of chemical admixture(SP) by weight of binding materials produced the excellent quality of structural concrete. Conversely, the replacement level of WSF can be limited up to 30%, Further, add into the concrete will affect the strength. From the test results observed that the 10% of MP, 20 % of WFS with 1.5% of GSF along with 1.5% of SP in concrete produced the higher compressive strength was 34.20, 39.90 and 42.50 N/mm 2 at 7, 28 and 56 days respectively, the strength was increased up to 7.40% than compared to controlled concrete. Also, a higher amount of bending stress was measured from 3.30 to 4 .57 MPa at 28 days for various mixes of concrete and the ultrasonic pulse velocity values are recorded between 3630 to 4030 m/sec for various mixes at 28 days. Finally, the durability measurement of RCPT and also material characteristics test on the modulus of elasticity of concrete were studied systematically.

“…However, it cannot be attributed only to this substitution, since the w/c ratio is not same (the IOP-sludge mortar contains more water and thus its negative impact can be expected). On the other hand, [11] explain that the gain in strength is due to reactions being so significant that they overcome the negative effect of greater w/c ratio in mortar mixes, but only up to 60% substitution. When marble powder is used to substitute more than 60% of sand, the pores formed due to excess of water are sufficient to reduce the compressive strength (however, these results are for the marble powder as fine aggregate).…”

“…As for sludge, various kinds have been investigated for application as filler in mortars: sludge from readymixed concrete plants as a substitute for limestone fillers [9], sludge from water treatment plants with different levels of replacement for natural sand [10], and marble powder as a replacement for conventional river sand in cement mortars [11].…”

This paper focuses on the use of sludge, which is currently a landfilled sand-like material left over from the processing of iron ore (IOP), representing an environmental burden. The incorporation of the material into some building mixtures like mortar or concrete can bring both environmental and technical benefit through the improvement of some properties of final mixture. Through the realization of the experiment programme, the authors have contributed to the knowledge about IOP and have determined the impact of this material on the properties of mortar mixture. This material is characterized using chemical, mineralogical, and granulometric analysis and then applied as 100% replacement of silica sand in standard mortar mixture. Basic physical-mechanical parameters (water demand, flexural strength, compressive strength) were tested. For the strength characteristics, both the samples with IOP sludge and samples with standardized sand (reference sample) were subjected to testing for a long-term period (14, 28, 270, and 365 days). Moreover, the capillary moisture was measured for 28-day old samples. Mortar prepared with IOP sludge shows lower compressive strength compared to the reference mixture throughout the overall time development, although the values themselves are sufficient for practical application. The flexural strength was found to be even better. The performance of the IOP sludge can be deemed as promising for practical applications when used in cement mortar.
