HiLab
· The High strength Low fines aggregate base, known as HiLab, has been in use by the agency as part of maintenance rehabilitation work and in trial sections over the past eight years, but this is the first time it is being used over a significant project length. HiLab is a pavement system modelled on the original Macadam pavement design philosophy, pioneered by Scottish engineer John Loudon ...

Stone Aggregate Testing Laboratory | Sigmatest
Organic Impurities: This test helps in determining the presence of organic compounds aggregated to use in cement mortar or concrete. The test provides a quick, relative measure to determine if further tests of the fine aggregate are necessary before approval for use. Test Method: IS: 2386 (P2)1963.
Importance of Aggregate Gradation of concrete slab
· FineAggregate Grading. Grading Requirements of ASTM C 33 or AASHTO M 6/M 43 permit a relatively wide range in fineaggregate gradation, but specifiions by other organizations are sometimes more restrictive. The most desirable fineaggregate grading depends on the type of work, the richness of the mixture, and the maximum size of coarse aggregate. In leaner mixtures, or when .

Fine Aggregate: Definition, Size, Density and Properties ...
Fine aggregate is the essential ingredient in concrete that consists of natural sand or crushed stone. The quality and fine aggregate density strongly influence the hardened properties of the concrete.. The concrete or mortar mixture can be made more durable, stronger and cheaper if you made the selection of fine aggregate on basis of grading zone, particle shape and surface texture, abrasion ...
Silt Content Test for Sand (Fine Aggregate)
Find out silt content in sand (fine aggregate) Apparatus required. 250 ml measuring cylinder; Water; Sand Tray; Test Procedure. First, we have to fill the measuring cylinder with 1% solution of salt and water up to 50 ml. Add sand to it until the level reaches 100 ml. Then fill the solution up to 150 ml level.

Fine Aggregate Specific Gravity • ASTM C128 – Dry aggregate – Soak in water for 24 hours – Spread out and dry to SSD – Add 500 g of SSD aggregate to pycnometer of known volume • Prefilled with some water – Add more water and agitate until air bubbles have been removed – Fill to calibration line and determine the mass of the pycnometer, aggregate and water – Empty aggregate ...
Aggregates for Concrete
aggregates cannot be overemphasized. The fine and coarse aggregates generally occupy 60% to 75% of the concrete volume (70% to 85% by mass) and strongly influence the concrete's freshly mixed and hardened properties, mixture proportions, and economy. Fine aggregates (Fig. 51) generally consist of natural sand or crushed
Specific Gravity and Absorption of Fine Aggregate
Place a portion of the partially dried fine aggregate loosely in the mold by filling until overflow occurs and heaping additional material above the top of the mold by holding it with the cupped fingers of the hand holding the mold. Lightly tamp the fine aggregate into the mold with 25 light drops of the tamper. Each drop should start about 5 mm ( in.) above the top surface of the fine ...
