well-printed specimens was a little higher( little larger) at 2350 kg/m3. This was likely because the concrete hopper was gently vibrated before delivery of the fresh concrete‚ and the pipe and pump system also provided a small pressure during extrusion. A similar trend occurred in a previous study on wet-spayed mortars (Austin et al.‚ 2000; Goodier et al.‚ 2008). Although this high performance printing concrete has only a sand aggregate‚ the density is much higher( much larger ) than that of ordinary mortars

Ash in Self-Compacting Concrete Coal Bottom Ash has gained a great consideration as an alternative for replacing fine aggregates. Coal Bottom Ash has physical characteristics are same as that of naturally found sand which makes it suitable for replacing sand in concrete. Coal Bottom Ash represents good pozzolanic element reactivity when it comes in contact with finer elements. Many researchers in their research work claimed that the properties of Self-Compacting Concrete comprised of 10% replacement

HIGH-PERFORMANCE CONCRETE Imagine a footbridge as long as a football field with a platform as thick as your hand. Or a 6’ x 10’ sheet just 1 inch thick that bends as it continues to support a 2‚000 lb car. Working in collaboration with Rhodia and Bouygues‚ Lafarge has developed a whole new family of concretes called Ductal. These concretes have high compressive and flexural strength‚ and their special characteristics enable the achievement of outstanding architectural feats. Ductal concrete incorporates

Sampling of aggregates - General Quality control tests are routinely carried out on representative samples of aggregates to ensure that any variation in quality is within the specification limits. The need for representative samples cannot be over-stressed; otherwise the test results may misrepresent the characteristics of the aggregates. Sampling operations
