Reliability estimates of unconfined compressive strength values from laboratory results for specimens compacted at British Standard Light (BSL)for compacted quarry dust treated black cotton soil using cement for road sub – base material was developed by incorporating data obtained from Unconfined compressive strength (UCS) test gotten from the …
Quarry dust was acquired from a local construction-oriented quarrying company and integrated into both the geopolymer and cement-based systems. Raw QD was pre-processed by air-drying in an oven at 105 °C for 24 h and then manually ground using pestle and mortar, to obtain an average particle size of 90 μm.
The materials used in this study are cement, sand, coarse aggregate, rice husk ash, and quarry dust. Ordinary Portland cement of 53 grade according to IS:269, river sand and crushed granite stones according to IS:383. The quarry dust was sourced from the granite crushing process. The raw rice husk (RH) was sourced from the rice mill.
The proportion of lateritic sand was varied from 0% to against quarry dust at intervals of 25%, using concrete mix of 1:1.5:3 and water/cement ratio of 0.65.

The empirical models developed in this study can be used to predict the compaction characteristics and CBR of cement stabilized soil-quarry dust mixtures. 3D variation of liquid limit with quarry ...
Consequently, this contributes to improve the strength of concrete. Through reaction with the concrete admixture, Marble sludge powder and quarry rock dust improved pozzolanic reaction, micro ...
Quarry Rock Dust can be defined as residue, tailing or other non-voluble waste material after the extraction and processing of rocks to form fine particles less than 4.75mm.
The partial replacement of quarry dust gave a 28 days' peak compressive strength at 40% replacement level and decreases for 50% replacement. Figure 3 shows the compressive strength relation for both normal concrete and quarry dust concrete, at the age of 28 days for M30, M25, and M20 grades of concrete for different w/c ratios of 0.45 …
Quarry dust (QD) was also used with normal Portland cement, silica fume and fly ash to prepare six types of concrete mixes which are designated as shown in Table 2. NPC concrete was considered as the control concrete. Quarry dust was used to replace 20% and 40% of sand respectively in preparing the concrete mixes containing …
D. Quarry Dust: The dust is selected from the nearest source as raw materials without any processing of the dust from the quarry. E. Mixing of the Materials: The normal grade of the concrete that is used is M20 for normal construction purposes in India[4]. The mix deign is done separately for the quarry dust using the minimum void
There are many studies on the effects of quarry dust, such as marble dust, granite dust, crushed rock dust, and limestone powder, on the bleeding and segregation of cement-based composites [77,78,79,80,81]. In all the studies examined, it was emphasized that the use of non-pozzolanic fillers in mortar or concrete mixtures increased bleeding …
Concrete with 50 % river sand and 50 % quarry dust performed better in flexure for both Bamboo Reinforced Concrete (BRC) and Steel Reinforced Concrete (SRC) at 28 days with strengths of...
Consequently, this contributes to improve the strength of concrete. Through reaction with the concrete admixture, Marble sludge powder and quarry rock dust improved pozzolanic reaction, micro ...

The compressive strength of concrete with waste quarry dust included as cement replacement was evaluated at 7, 14, 28, 60, 90, and 120 days. In general, lower compressive strengths were obtained compared to their equivalent reference mix, as the waste quarry dust content increased for the constant water-to-binder ratio mixtures.
Abstract: Quarry rock dust is investigated as fine aggregate in replacement with sand in cement concrete admixture, as the properties. of the rock dust are suspected to be as good as sand. This ...
