The artificial aggregate-based geopolymer is type of porous aggregate and vacuum impregnation method that is an effective way to improve the properties by …
Substitution of 25, 50, 75, and of PET artificial aggregate gave decreases in compressive strength of 30.06, 32.39, 41.73, and 44.06% of the compressive strength of the standard concrete (18. ...
The RCP artificial aggregates only require sealed storage and natural curing. The artificial aggregates are nearly spherical and exhibit good early strength performance. The compressive strength of each group reaches 75% to 92% of the 28d strength at 3d, and the compressive strength of a single particle reached 8.59 MPa at 28d.
The resulting aggregate had a bearing capacity of single grain of 73.83 N and a water-resistance coefficient of 0.67. After the above aggregates were treated with Na 2 SO 4 (activator) at 2%, the bearing capacity and water-resistance coefficient of the aggregates increased by 47.00% and 11.94%, respectively. The performances were …

The concrete mix was designed for M30 grade by replacing natural coarse aggregates with FAA by 30, 50, and 70%. Table 5 shows the mix proportions obtained for concrete of different replacements. According to the mix design, the ingredients were mixed and cast into 0.15 × 0.15 × 0.15 m cubes, cylinders of 0.15 m diameter and 0.30 m …
Artificial sand, also known as machine-made sand, is a substitute for natural sand in the construction industry. It is produced by crushing rocks, quarry stones, or larger aggregates into small ...
To overcome these difficulties Akashganga had developed artificial sand making machine which makes sand similar to river sand. The sand manufactured by our machine is having good surface texture and edges of the granules of the sand are rounded. The particle shape of fine aggregates is very important for making concrete.
The highest strength of the aggregates was only about 2.3 MPa. Yi Jiang [ 21] adopted recycled concrete powder, cement, slag, and Ca (OH) 2 to prepare artificial aggregate, and CO 2 curing was used to obtain the maximum aggregate strength up to about 3 MPa. The strength of concrete at this time was 31.8 MPa.
Considering the above-mentioned concerns, turning unutilized wastes into artificial aggregates for use in concrete has become a worthy topic. Currently, the common manufacturing methods of artificial aggregates include cold bonding and sintering (Bijen, 1986).The cold bonding method typically utilizes cementitious materials …
Abstract. This present work provides a study of several successful approaches in producing artificial aggregates using a pelletiser machine and the parameters affecting efficiency. These aggregates were contrived from substances of nature such as fly-ash, GGBS, Rice husk ash, volcanic ash, etc. Different sets of …
Aggregates can either be natural or manufactured. Natural aggregates are generally extracted from larger rock formations through an open excavation (quarry). Extracted rock is typically reduced to usable sizes by mechanical crushing. Manufactured aggregate is often the byproduct of other manufacturing industries.
Such sand can be used for all types of construction work, Concreting, Plastering etc and is better substitute to river sand. V.S.I. Crushers is a most economical machine for Crushing Stone in Cubical shape and manufacturing artificial sand. In this machine the particles are thrown at a high speed.
