��Ѻ��ا���ǵ�����ҧ�ء������ҧ����ö��ҹ�ҵðҹ����ҧ��ǧ�� ABSTRACT This project is a study of
unconfined compressive strength of Supanburi saline soil , saline soil with
Portland cement type 1 and saline soil with Portland cement type 1
and Renolith. The ratio of cement added is 7 percent , 10 percent and 13
percent of dry saline soil weight . The ratio of Renolith added at 3 percent ,
6 percent and 9 percent
of cement weight at curing time of the mixture is 7 days , 14 days and 28 days.
The saline soil at salinity of 0.2 ms/cm , 5.5 ms/cm and 18 ms/cm has been
tested by optimum
moisture content (O.M.C.), The results of all specimens of the 7 day-curing is
shown that the unconfined compressive strength of saline soil at salinity of 0.2
ms/cm , 5.5 ms/cm
and 18 ms/cm is 7.78 ksc , 10.7 ksc and 5.45 ksc respectively. The strength of
unimproved specimens will not meet the standard of the Highway Department (17.5
ksc) and
improved specimens meet that of the Highway Department. �����
