M.test#6: Compressive Strength Cylinders

M.test#6: Test for compressive strength of cylinders or cubes (AASHTO T 22-92) (ASTM C39)

This test method covers determination of compressive strength of cylindrical concrete specimen such as molded cylinders and cubes . It is limited to concrete having a unit weight in excess of 800 kg/m^3

M.Test#5 : Making and curing compressive test specimens in Field AASHTO T 23-93

M.Test#5 : Making and curing compressive test specimens in Field AASHTO T 23-93

This test method covers procedures for making and curing cylindrical and prismatic beam specimen from representative sampled fresh concrete for a construction project. The concrete used to make molded specimens shall have the same levels of slump , air content , and percentage of coarse aggregate as represented in concrete 

M.test#4 Making and curing concrete test specimen in lab AASHTO T 126-93

M.Test#4: Making and curing compressive test specimen in lab AASHTO T 126-93

This test method covers procedures for making and curing test specimen of concrete in laboratory under accurate control of materials and test conditions using concrete that can be consolidate by rodding or vibration as described here

M.test#2 Air Entrained ASTM C138

M.test#2 : Test method for Air Entrained ASTM C138

This test method covers determination of the air content of freshly mixed concrete from observation of the change in volume of concrete with change in pressure

S.test#8 : Classification Of Soil

S.Test#8 : Classification of soils AASHTO M 145-91

This recommended practice describes a procedure  for classifying soils into seven groups based on lab determination of particle-size distribution. Liquid limit,plastic limit , and plasticity index evaluation of soils within each group index , should be useful in determining relative  quality of soil material for use in earthwork structure , subbase , subgrade or others .

S.test#4 California Bearing Ratio

S.Tests#4: California Bearing Ration AASHTP T 193 - 93 ASTM D1883

This test method covers the determination of the California Bearing Ratio ( CBR) of pavement subgrade , subbase and basecoarse materials  rotary compacted specimen . The test method is primarily intended for - but not limited to - evaluating the strength of the cohesive materials having maximum particle sizes less than 19mm.It is the load to penetrate a cylinder with some speed to 0.1 in. or 01.2 in
