M.test#3 : test method for unit weight ASTM C138

M.test#3 : Test method For Unit Weight ASTM C 138


This test method covers the weight of concrete per meter cube from air entrained machine
We can find unite weight of concrete by dividing the weight of concrete to volume of machine of machine g/cm*3

SUMMARY OF THE SECOND CHAPTER : SOIL TESTS FOR HIGHWAY PURPOSES

Soil engineering is vital within civil engineering. The properties of a soil influence and affect a structure when being built and as a result the soil must be tested before designing

We end this chapter of "soil tests for highway purposes" with our 8 posted tests , and our next stop is " Mix Design of Concrete ACI 211"

A minor reminder of what the posted tests in this photo 

S.TEST#3 Density Of Soil using 100lb. Rammer

S.Test#3: Density relation of soil using 100lb. Rammer AASHTO T99

this test method is intended for determining the relationship between the moisture content and density of soils when compacted in given mold of a given size with 10lb rammer dropped from a height of 457mm. Four alternate procedures are provided 

S.test#1 : SandCone

S.Test#1: Density and unit weight of soil (SAND CONE) AASHTo 191 - 93

This test method covers the determination of compaction of the field if it's done by sand cone
