S.test#2: Moisture Content In Soil

S.test#2: Laboratory Determination of moisture content of soil AASHTO T265-91

This procedure is used to determine the total moisture content of a soil . The soil is dried to remove all free moisture . This test measures the weight of the moisture removed from the soil .

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 

Summary of the First Chapter : MATERIAL TESTING

The core of any civil engineering design is the understanding of the behavioural , physical , and mechanical properties of the materials used . 


Today we have finished the " Material testing" category in which we have posted 13 tests , and our NEXT stop is :

" SOIL tests for highway purposes " 

A minor reminder of the tests ,that have been posted, in this photo 

test#13 Soundness of aggregate ASTM c - 88

Test #13 Soundness of aggregate by sodium sulfate ASTM C - 88

This test method covers the testing of aggregates to estimate their soundness when subjected to weathering action in concrete by repeated immersion in saturated solution of sodium or magnesium followed by oven drying 

Test#12 Material Finer 75 Micron Sieve (ASTM C117-90)

Material finer than 75mi (ASTM C 117-90)

This test method covers determination of the amount of material finer than 75 micron ( No. 200) sieve in aggregate by washing clay particles and other aggregate particles that are dispersed by the wash water  as well as the water soluble materials , will be removed from aggregate during test 

Test#11 Fineness Modulus

Determination of fitness modulus on fine aggregate (AASHTO M6)

Fitness Modulus results from a calculation on using data from a sieve analysis. The sieves used for sand are typically  the 0.15mm (No.100) 0.30 (No.50) , 0.60mm(No. 30 ) , 1.18mm (No.16) , 2.36mm (No.8) and the 4.75mm (No.4)

Test#10: Clay Lumps and friable particles (AASHTO T 112 - ASTM C 142)

Clay Lumps and friable particles (AASHTO T 112 - ASTM C 142)

This test method covers the approximate determination of clay lumps  and friable in natural aggregates
