The purpose of this study is to evaluate the possibility of using granulated pumice as an alternative to fine aggregate in production of lightweight cement mortar. The cement/pumice fine aggregate ratio is 1:3 for pumice aggregate mortar. The water content is determined by flow table test. Compressive and flexural strength, freeze-thaw …

Fine aggregates are usually made of sand or crushed stone, whereas coarse aggregates can be up to 1.5 inches in diameter. One digs up sand or natural gravel from a lake, river, or seabed and then processes the aggregate.

Quarry dust can be partially used as an alternative to river sand, as fine aggregate in concrete production. It is basically a by-product of stone crushers produced during the crushing and screening process of coarse aggregates.

The influence of W/S (water-to-solids) ratio and the influence of various fine aggregates, namely, river sand (R), manufactured sand (M) and construction demolition waste (D) on the various geopolymer system (GP) and on the strength characteristics, are highlighted.

Use of pond ash to partially replace conventional fine aggregate in concrete mix, not only provides an effective solution to scarcity of sand / crushed stone, but also helps reduce the impact of ...

This research provides the reference for the application of AGW as a fine aggregate replacement to produce fly ash geopolymer mortar as green building materials with excellent thermal insulating and fire-resistant applications.

This study aims to examine the use of bamboo as an alternative reinforcement in concrete beam made from sand beach's as fine aggregate. Sand beach of loto is one of three quarry sources chosen as a fine aggregate in making test specimens reinforced concrete beams as subjected study.

Three proportions of foundry sand were substituted for fine aggregates. The replacement percentages for fine aggregate were 10, 20, and 30 percent by weight.

However, the extraction and consumption of natural aggregates, such as river sand and gravel, have negative impacts on the environment and human health. Therefore, there is a need to find alternative sources of aggregates that are more sustainable and eco-friendly.

Compared to natural sand, chicken feather sand (CFS) works as an eco-friendly resource. In this study, the chicken feather content ranged from 5% to 25% of the total volume of fine aggregates.

In this study, effect of foundry sand as fine aggregate replacement on the compressive strength of concrete with a M30 mix proportion investigated at different limited curing periods (7 days, 14 days and 28 days).

This paper is part of a study investigating the structural characteristics of concrete using various combinations of lateritic sand and quarry dust as complete replacement for conventional river sand fine aggregate. Samples of concrete (eg. cubes) were made using varying contents of laterite and quarry dust as fine aggregate.

The use of alternative and locally available materials is encouraged in the construction industry to improve its sustainability. Desert regions with shortages in freshwater and river sand as fine aggregates in concrete have to search for alternative materials such as seawater, dune sand, and waste glass powder to produce lightweight …

Overcome this crisis [ 3 ]; alternatives have come up for the industry to bank on of which manufactured sand or M-sand and quarry dust, both observed to be the most reasonable one to supplant river sand [ 4 ].

This study aims to examine the use of bamboo as an alternative reinforcement in concrete beam made from sand beach's as fine aggregate.

The fine aggregate was natural river sand with a fineness modulus of 2.66 and sizes between 0.15 and 4.8 mm. The silica fume was a supplementary cementitious material to improve particle packing ...

Construction industries around the world are facing many difficulties in obtaining good-quality fine aggregates for concrete and mortar due to a shortage of river sand.

Construction industries around the world are facing many difficulties in obtaining good-quality fine aggregates for concrete and mortar due to a shortage of river sand. This problem leads the resea...

This reinforces the feasibility of desert sand as a viable alternative to traditional fine aggregate in concrete production. Liu et al. [18] researched the pore structure and mechanical properties of concrete made from desert sand, specifically investigating the effects of exposure to high temperatures.

The proportions of the fine aggregate (sand), coarse aggregate (gravel), cement and water are varied to give concretes of different strengths and workabilities .

The durability performance of the mortar with alternative fine aggregates is comparable with those of standard sand.

Increased construction activity around the world to meet rising economic demand depletes natural resources, mainly river sand. River sand remains the first choice for fine aggregate because of its superior quality and the lack of a suitable alternative. This situation resulted in haphazard sand exploration. Also, demolition waste generated …

In this study, replacement of sea sand instead of river sand as 20%, 30%, 40% and 50% respectively as partial replacement for fine aggregate. Analysis of the parameters such as compressive strength, water absorption were investigated and compared with conventional concrete. It is found that sea sand addition does not …

Knowledge Institute of Technology. Manufactured sand blended with natural sand in the ratio of 70:30 can be used as fine aggregate in concrete, which shows the better performance than conventional ...

This literature review examines the effects of laterite type on the compressive and flexural strengths of concrete when utilizing laterite-sand fine aggregate.

The most commonly used in construction is a fine aggregate from river sand or pit sand. Fine and coarse aggregates constitute about 75% of total concrete by volume. It is, therefore, essential to obtain right type and best quality aggregates at sites, because the aggregate forms the main components of the concrete mixture or mortar 3.
