The characteristics of concrete containing fine crushed glass during its processUse of crushed granite fines or crushed rock fines as an alternative to sand in concrete production was also reported [7]. In Makurdi conforming to IS: 383 is being use. The Flakiness and Elongation Index were maintained well below 15%. e) Fine aggregate Those fractions from 4.75 mm to 150 microns are termed as fine aggregate. The river sand is used in combination as fine aggregate conforming to the requirements of IS: 383.This project fully characterizes microfines and evaluates simple tests for predicting performance in concrete. 17.

Sand is a unique raw material for the construction industry at present quarry dustCivil Engineering Department 2006) demonstrated that the use of recycled concrete fines could offset some or all of the delayed strength‐gain effects from cement‐GGBFS blends. Current work appears to indicate that the use of such fines could allow for increased cement replacement with no additional reduction in early strength gain.The alternative fine aggregates satisfies the requirements as alternatives to river sand. • Crushed rock sand,

for a given workability requirement M35 Shales and Slates 10 3 RECYCLED AGGREGATES 10Crushed Sand (Manufactured Sand) Better quality as compared to natural sand because it is manufactured in a controlled environment. Natural Sand. The quality of natural sand deferrers though they may be from the same river bed. 05. Grading Zone. Crushed Sand (Manufactured Sand) Manufactured to conform to zone II.3.2 COMPRESSIVE STRENGTH - Compressive strength of concrete mixes with various percentage of marble dust as replacement of cement at age of 7 days and 28 days respectively are shown in Fig.3 and Fig.4. From Table 10 and 11 it can be observed that with the replacement of cement with marble dust for 5% & 10% there is an increase in the strength at 7days as well as at 28 days.H.
