Abstract. High chloride ion concentration is the main obstacle to use sea sand as the fine aggregate for reinforced concrete structures. The chloride ion on the …

In the making of concrete, up to 70–80% volume is constituted by the aggregates that help in hardening. M-sand was used in this project as a fine aggregate with an all-out size of 4.75 µm is confirming to zone II grade. Graded crushed rock is used as a coarse aggregate throughout this project.

FINE AGGREGATE :- The size of aggregate 4.75mm & smaller is called fine aggregate. Sand is generally considered to have a lower size limit of about 0.07mm. Material between 0.06-0.002 mm is classified as silt. Particles smaller than 0.002 mm are termed as clay. Loam is a soft deposit consisting of sand, silt & clay in about equal …

The ultimate objective of this research is to study the practical utilization of sea sand as fine aggregate partially and to study the properties of mineral extracted sea-shore soil. …

5. Aggregates 5 Fine aggregate (Sand) •Particles having diameter in between 4.75 mm to 75 micron is called Sand. •Fills the voids within coarse aggregates •Assists in hardening of cement by allowing water to seep through its voids •Minimizes shrinking and cracking of concrete •Economizes concrete by varying its proportion for …

Moreover, the land resources in these areas are precious, and the cost of landfill disposal is high. For this reason, while using sea sand to replace river sand, waste glass can also be crushed and be used as coarse aggregates to prepare a new type of seawater sea sand glass aggregate concrete (SSGC).

Stone dust can substitute river sand as fine aggregate in concrete. Ceramic waste can replace 10–20% of coarse aggregates without impacting material structure. Ceramic waste can replace coarse aggregates [17]. The mechanical characteristics of normal concrete with quarry dust (2011). In the experiment, quarry dust replaced sand …

Concrete with higher seashell ratio has lower physical and mechanical properties. •. Ground seashell aggregate can replace up to 20% natural fine aggregate in concrete. •. Up to 50% seashell as a partial coarse aggregate can give normal-weight concrete. •. Current data on durability of seashell aggregate concrete indicate varied …

River sand is currently the main sand used for construction, but the extraction of river sand as fine aggregate has adverse effects on river ecosystems, navigation, and flood control [].Now we should look for the new aggregates which are more environmentally friendly [].Recently, a number of new methods have been developed for …

The utilization of sea sand as an alternative to fine aggregate in the manufacture of concrete is motivated by the availability of sea sand in …

Findings. The results showed a reduction in compressive strength when 50 per cent of sea shells were used as an aggregate replacement, for both sand and gravel, compared to the control sample. Crushed and graded sea shells used in concrete displayed a lower porosity/permeability than plain concrete.

Size of Fine Aggregate Is. The size of fine aggregates is defined as 4.75mm or smaller. That is, aggregates which can be passed through a number 4 sieve, with a mesh size of 4.75mm. Fine aggregates include things such as sand, silt and clay. Crushed stone and crushed gravel might also fall under this category.
