The Importance of Fineness Modulus| Concrete Construction

Jan 01, 1994 · ASTM C 33 requires the FM of fine aggregate to be between 2.3 and 3.1. The higher the FM, the coarser the aggregate. Fine aggregate affects many concrete properties, including workability and finishability. Usually, a lower FM results in more paste, making concrete easier to finish. For the high cement contents used in the production of high

Mix design and fresh properties for high-performance

Jan 19, 2012 · This paper presents the experimental results concerning the mix design and fresh properties of a high-performance fibre-reinforced fine-aggregate concrete for printing concrete. This concrete has been designed to be extruded through a nozzle to build layer-by-layer structural components. The printing process is a novel digitally controlled additive manufacturing method which …

CONCRETE BASICS A Guide to Concrete Practice

This gives a stronger and denser concrete. Rounded aggregates give a more workable mix. Angular aggregates make concrete harder to place, work and compact, but can make concrete stronger. STORAGE Aggregates should be stored where they will stay clean, separated from other materials and dry. If the aggregates are very wet use less water in the mix.

Stormwater Best Management Practices: Concrete Washout

Construction Sites. Concrete and its ingredients. Concrete is a mixture of cement, water, and aggregate material. Portland cement is made by heating a mixture of limestone and . clay containing oxides of calcium, aluminum, silicon and other metals in a kiln and then pulverizing the resulting clinker. The fine aggregate particles are usually


Slump is a measure of concrete consistency or fluidity. Consistency is the ability of freshly mixed concrete to flow. For given proportions of cement and aggregates (without admixtures), the higher the slump, the wetter the mix. Four-inch (4") slump is very common with normal weight concrete and is a good average slump for pumping.

Pumping of Concrete

When flowing concrete is being pumped, an over-cohesive mixture with high sand content is recommended. For lightweight aggregate concrete, pumping can fill up the voids in the aggregate with water, making the mixture dry.

No Fines Concrete | Boral

No Fines Concrete is literally that—concrete made without fine aggregate so it has high permeability and drainage capacity. Boral No Fines permeable concrete, when placed correctly, absorbs rainwater and facilitates natural runoff into the ground or storage tanks. It can also minimise saturation of the storm water network, reducing the risk of flooding in heavy rain events.


Grout for masonry construction is a high slump material with a flowable consistency to ease placement and facilitate consolidation. Both the Specification for Masonry Structures (ref. 7) and ASTM C476 require grout to have a slump between 8 and 11 in. (203 – 279 mm).

Materials For High Density Concrete Production

To achieve the required concrete density to absorb the radiation a combination of high-density aggregates steel shot (fine aggregate) and hematite iron-ore (coarse aggregate) was used. The use of high density aggregates increased the cost for 40 Mpa concrete from approximately R370.00 to R7 600.00 per cubic metre of concrete in 1996. (A.

Aggregates for Concrete - Memphis

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 influ-ence the concrete's freshly mixed and hardened proper-ties, mixture proportions, and economy. Fine aggregates (Fig. 5-1) generally consist of natural sand or crushed

Look at the three major characteristics of fine aggregate
