    Erosion of soil

    Great Eire...here the erosion will be controlled by stone pitching and then motor grouting will be done. But this issue come before stone pitching. How and what material will be good to fill the space beneath the chute. Becouse if we dump soil thn how we will compact that

    Sand Equivalent

    Yes sir your thoughts are nice...but why not to the nearest small whole number? Why always next whole number..example 7.1 should be reported as 8 why not 7.

    Sand Equivalent

    Why during sand equivalent test the reported value should be taken to the nearest higher whole number..is there any scientific reason for that or its just for the purpose of ease..thanks
