·Type of aggregate = uncrushed size of aggregate = 20 mm and specified slump = 30 60 mm Therefore from Table free water content = 180 kg/m 3 Step 4 Cement content Cement content = free water content/free w/c ratio = 180/ = 367 kg/m 3
The aggregate type and quality are important factors for determining the required treatment/ replacement thickness The overall objective in this project has been to characterize strength stiffness and deformation behavior of three crushed and uncrushed aggregate materials limestone dolomite and uncrushed gravel commonly used in

Step 5 Estimation of Coarse Aggregate proportion From Table 3 of IS 10262 2009 For Nominal maximum size of aggregate = 20 mm Zone of fine aggregate = Zone II And For w/c = Volume of coarse aggregate per unit volume of total aggregate = Table for correction in estimation of coarse aggregate proportion
The ACI 08 method did not make provision for uncrushed aggregate in its design method implying that comparison could not be made in that regard The use of high strength concrete HSC has increased all over the world Among the factors that justify this increased use is the strength increase for structural aspects and durability

·The coarse aggregate can be defined into three categories according to the source Uncrushed Gravel or Stone produced by natural rock disintegration Crushed gravel or stone is obtained by grinding hard stone or gravel Partially Crushed Gravel or Stone which is created by combining the two aggregates above
·The aggregate they produce has a top size of ¾ inches meeting ASTM C33 requirements for #67 aggregate Cemstone s first large project will be constructing the retaining walls for an extension of the light rail trains between St Paul and Minneapolis The project will use 10 000 cubic yards of 50% CCA and 50% virgin aggregate concrete
·Fine aggregate characterized by its passage through a mm IS sieve is further sub divided into four grading zones Zones 1 4 with Zone 4 being the most fine Examples of fine aggregates include concrete or masonry sand Coarse aggregate is categorized based on its particle size and shape which can be uncrushed crushed or partially
From the laboratory test of strength determination it was explored that uncrushed aggregate provide more strength 22% at 28 days than crushed aggregates for medium grade concrete Similar results were found for low grade concrete cube strength at 28 days up to 15 Mpa in a previous study relevant to mention uncrushed aggregate is cheaper
