Cement is considered one of the most important building materials around the world. It is mainly used for the production of concrete. Concrete is a mixture of inert mineral aggregates, such as sand, gravel, crushed stones, and cement. Cement consumption and production is closely related to construction activity, and therefore
The use of plant fibers in cementitious composites has been gaining prominence with the need for more sustainable construction materials. It occurs due to the advantages natural fibers provide to these composites, such as the reduction of density, fragmentation, and propagation of cracks in concrete. The consumption of coconut, a …
researchers by narrowing down the literature search scope. Whilst mathematics learning is posited as a developmental progression in the direction of concrete-to-abstract, various related studies have hitherto been conducted. The findings of the previous studies have been synthesised by conducting meta-analysis and systematic literature

According to Table 1, it can be found that the existing review papers has been slightly out-of-date.Most of the brick-related reviews covered the publication up to 2013. Although Boltakova et al. [13] reviewed the studies up to 2015, whereas it merely focused on the studies done by Russian researchers, neglecting the other relevant …
This led the researchers to look for possible partial cement replacement by investigating the potential use of rice husk in making concrete hollow blocks. The researchers created concrete hollow blocks (CHB) at three different percentage of rice husk (RH) powder addition from 0%, 5%, and 10%.
The massive use of concrete due to boom in various infrastructure development has led to over-extraction of river sand from the riverbed.

The concrete samples were cast using 150mm x 150mm x 150mm mould, and the target strength was M20. The Compressive Strength of M20 (0% RHA) concrete at 3, 7 and 28 days are 14.50, 20.50 and 30.3 respectively. Whereas on replacing cement with 20% of RHA it comes out to be 13.40, 21.60 and 30.70 respectively.
