Concrete

  1. 1. www.desiredesigning.in
  2. 2.  Construction material  Mixture of Portland cement, water, aggregates, and in some cases, admixtures.  The cement and water form a paste that hardens and bonds the aggregates together.  often looked upon as “man made rock”.  versatile construction material, adaptable to a wide variety of agricultural and residential uses.  Strong, durablele, versatile, and economical. www.desiredesigning.in
  3. 3.  Can be placed or molded into virtually any shape and reproduce any surface texture.  The most widely used construction material in the world.  In the United States almost twice as much concrete is used as all other construction materials combined.  The ready-mix concrete producer has made concrete an appropriate construction material for many applications. www.desiredesigning.in
  4. 4.  Water  Aggregates  Reinforcement  Chemical admixtures  Cement www.desiredesigning.in
  5. 5.  Great water is basic for quality cement.  Ought to be adequate to drink- - free of waste, natural matter and unnecessary chemicals as well as minerals.  The quality and different properties of cement are exceptionally subject to the measure of water and the water-concrete proportion. www.desiredesigning.in
  6. 6.  Totals involve 60 to 80 percent of the volume of cement.  Sand, rock and smashed stone are the essential totals utilized.  All totals must be basically free of residue as well as natural matter. www.desiredesigning.in
  7. 7.   www.desiredesigning.in
  8. 8.  Crystalline compound of calcium silicates and other calcium mixes having water powered properties.  Considered pressure driven in view of their capacity to set and solidify under or with overabundance water through the hydration of the bond's synthetic mixes or minerals  Uses Main use is in the fabrication of concrete and mortars  Modern uses -Building (floors, beams, columns, roofing, piles, bricks, mortar, panels, plaster) -Transport (roads, pathways, crossings, bridges, viaducts, tunnels, parking, etc.) -Water (pipes, drains, canals, dams, tanks, pools, etc.) -Civil (piers, docks, retaining walls, silos, warehousing, poles, pylons, fencing) -Agriculture (buildings, processing, housing, irrigation) www.desiredesigning.in
  9. 9.  The ease with which freshly mixed concrete can be placed and finished without segregation.  Difficult to measure but ready-mix companies usually have experience in determining the proper mix.  Important to accurately describe what the concrete is to be used for, and how it will be placed. www.desiredesigning.in
  10. 10.  Solid that has been indicated, clustered, blended, set, and completed "letter- impeccable" can even now be a disappointment assuming dishonorably or deficiently cured.  Normally the last stride in a solid venture and, tragically, is regularly ignored even by experts. www.desiredesigning.in
  11. 11.  Curing has a major influence on the properties of hardened concrete such as durability, strength, water-tightness, wear resistance, volume stability, and resistance to freezing and thawing.  Proper concrete curing for agricultural and residential applications involves keeping newly placed concrete moist and avoiding temperature extremes (above 90°F or below 50°F) for at least three days.  A seven-day (or longer) curing time is recommended. www.desiredesigning.in
  12. 12.  Strength  Elasticity  Cracking  Shrinkage cracking  Tension cracking www.desiredesigning.in
