In fact, characterization results (Table 2) show that the obtained values of flakiness index and sand equivalent of recycled aggregates are consistent with the European standard [9].The value of finess modulus of natural sand is 1.95 according to European standard [10].It indicates that the sand is fine and may improve workability of …
After the concrete is poured and finished, there are a few methods that can be used to expose the aggregate, such as water washing, abrasive blasting, honing and acid etching, but when it comes to concrete countertops, whether pre-cast or poured in place, a Wet Polisher and Diamond Polishing Pads are most common. This process will …
In all the variations 10%, 20%, and 30% of aggregates were replaced by their volume. e-plastics and CS used in this concrete were shredded and gridded to achieve sizes similar to natural aggregate.
Marble by-products were used to replace coarse natural aggregates while the crushed mussel shells partially replaced fine aggregates. The mixes were studied to …
Our Mining & Quarrying Division supplies aggregates & washed sand to various concrete supply companies in Muscat & Sohar regions.
It gives good workability of SCC marble fine aggregate concrete. 2. Strength test indicates, 25% of marble fine aggregate in the self-compacting concrete gives the fair results for a curing period of 56 days and also it shows that increasing in curing days will increases the strength of marble fine aggregate concrete were compared from 14, 28 ...
Additions of marble aggregate to the concrete increases wear resistance of the paving blocks. [2] According to the test results, higher weight losses were observed in limestone powder series than in basalt and marble powder series. Also, as the self-compacting concrete mixtures were exposed to high temperature, limestone powder …
Originally established in 1984, we now lead the way as one of the largest manufacturers and suppliers of concrete products in Oman with our annual production capacities …
Self-compacting concrete (SCC) is a special, highly fluid type of concrete that is produced using chemical additives. It is easier to pour and reduces defects arising from workability. Waste marble dust is generated during the production of marble using different methods, or during the cutting of marble in processing plants; however, the …
The main objective of the following paper is to verify the possible applications of marble by-products obtained from the ornamental stone industry and mussel shells …
In this paper, CaCO3 waste marble dust (WMD) has been utilized in the production of concrete. Raw materials (Cement, Sand, WMD and Crush) were collected from Peshawar, Khyber Pakhtunkhwa, Pakistan. Concrete cubes were molded in the laboratory and investigated by XRD. Effect of WMD addition to the concrete was …

It is proved that this waste has a significant impact both on the people health and on the environment. Hence, research …
aggregate in concrete have benefited and aggregate water absorption ceramic and natural gravel respectively 0.55 and 0.23%. Concrete pavement tile from coconut shell, have more advantages such as very environmentally friendly, absorbs heat and save costs. Coconut shell is a good strength property compared with conventional pavement tiles.
Self-compacting concrete (SCC) is also seen as unsustainable since it uses a lot of natural resources. Recent researchers have focused on lowering construction costs and partially replacing cement with industrial waste.
