Grano is a fine-grained hard-wearing concrete. Think of it being an intermediate between a standard sand-cement mortar and a more familiar concrete based on a 10mm or 14mm coarse aggregate. ... roughly 6mm to dust and usually formed from stone such as limestone or granite (hence the name), but is increasingly 'supplemented' by recycled ...
The use of constant w/c ratio for all mixes resulted in a reduction in the workability when WMP was introduced as a sand replacement in concrete. As compared to SR-0, the overall reductions at 20%, 40%, 60%, and 80% replacement were found to be 26%, 65%, 93%, and , respectively. ... (2016) Reusing of marble and granite powders in self ...
Despite the variation in the effect of stone dust on concrete workability due to the different physical characteristics of SD found in the various mining companies around the globe, such as ...
The possibility of using granite dust as partial replacement to natural sand in reinforced concrete beams is evaluated in this paper through a series of experimental investigations.
An experimental study on the potential of granite dust as a filler in enhancing the mechanical performance of a hybrid basalt/glass (WB/GCSM) composite, which revealed a remarkable improvement in all mechanical properties was noticed for [WB/ GCSM/1GD], which recorded the highest mechanical performance among all WB/G CSM composite systems.
In this study, clay brick and granite waste were crushed and screened into two size fractions (0.15–2.36 mm for sand replacement and smaller than 0.15 mm for cement …
Granite dust cement replacement or addition of 5.0%, 7.5%, 10.0% and 15.0% were used. The test results showed an improvement on concrete compressive strength at 5.0% granite dust as cement ...
The results showed that a 20% replacement ratio of fine aggregate with marble and granite increased the compressive strength by 32% compared to conventional concrete; …
This present work is also an attempt to use Granite powder and Copper slag as partial replacement for Sand in M25 grade concrete. Attempts have been made to study the properties of concrete and some properties of Granite powder and Copper slag, their suitability of those properties to enable them to be used as partial replacement materials for ...
The effect of replacement of sand with granite dust on workability was measured by conducting slump tests. The results of slump test are presented in Table 4. It can be seen from the table that replacement of sand by granite dust decreases the workability of resulting concrete. This is in conformity with the results of earlier researches available.
The efficacy of the granite dust in replacing sand in concrete is explored followed by its ability to improve the geotechnical characteristics of clays of varying plasticity are explored.
Here, such correlation in the manufactured sand concrete with granite dust was compared with ACI 318 [27] and CEB-FIP MC 1990 [28] to verify the conformance. ... Concrete early strengths are reduced by introducing granite dust. When the replacement ratio is controlled within 20%, the manufactured sand concrete possesses higher long-term ...
Performance of various types of marble dust such as basalt concrete, river sand and granite concrete which is compiled in this study is suitable substitution of fine aggregates or cements. However, marble debris needs suitable treatment before its use. 2. When replacement is 50%, basalt and river sand concrete produce better slump value. 3.
Stone dust can substitute river sand as fine aggregate in concrete. Ceramic waste can replace 10–20% of coarse aggregates without impacting material structure. Ceramic waste can replace coarse aggregates [17]. The mechanical characteristics of normal concrete with quarry dust (2011). In the experiment, quarry dust replaced sand of the time.
Granite dust could valuably be incorporated as partial sand replacement in autoclave aerated concrete (AAC), thereby reducing health and environmental hazards, and controlling sand depletion by ...
powder, stone dust, and quarry waste are used in concrete mixtures [12]. Granite dust, nowadays, is one such com-monly known alternative [13]. Many researchers have studied the use of granite dust as a replacement for sand in conventional concrete. Prokopski et al. [14] have agreed that granite dust is suitable as a con-crete component.

Therefore, the compressive strength rises apparently with the percentage of granite dust in the concrete mix raised to 20 %. If the sand replacement level exceeds 25 %, the splitting tensile strength falls [[24], [25], [26], [27]].
Influence of replacement of sand with marble and granite dust on the strength behaviour on concrete was studied at curing ages 7 and 28 days and the results are compared with conventional concrete blocks. A 20% replacement of fine aggregates with marble and granite dust mixture resulted in 23.34% and

The control concrete values for 7, 28, 56 and 112 days were 3.50, 4.34, 4.89 and 5.44. It is evident that flexural strength continued to increase maximum up to 30% sand replacement with copper slag and granite dust at 28 days, beyond that it goes on slightly decreasing as copper slag and granite dust percentages is increased.
