EFFECT OF ACID WATER ON BASES AND SUB-BASES

ACTION DES EAUX ACIDES SUR LES FONDATIONS ET LES SOUS- FONDATIONS

TO STUDY THE CHEMICAL STABILITY OF ROAD CONSTRUCTION MATERIALS IN THE PRESENCE OF ACID WATER (BASES AND SUB- BASES). TO DETERMINE THE PERCENTAGE OF DISSOLUTION AND TO CALCULATE RESULTING SETTLEMENT. (1) ACTION OF ACID WATER WITH VARIABLE PH AT 3, 4,5, 6 AND 7 (STAGNANT MATERIAL IN ACID CAPILLARY WATER). (2) ACTION OF ACID WATER WITH CONSTANT PH (MATERIAL THROUGH WHICH FLOWS ACID WATER WITH A CONSTANT PH). TEST DURATION IS : 24 HOURS, 48 HOURS, 72 HOURS, 96 HOURS, AND 120 HOURS. LOSSES OF WEIGHT IN THE MATERIAL DUE TO CHEMICAL DISSOLUTION WILL BE CALCULATED BY BOTH METHODS AND THE DISPERSION OF RESULTS WILL BE ANALYSED.
