“…The trend for the normalized mass loss was found lowest for soil 3 which could be the reason that soil 3 had maximum amount of fines. Also, the trend followed by all soils is similar to observed by [3] i.e. with the increase in cement content the soil line of normalized mass loss goes down which is observed for all three soils tested.…”

“…IRC (2012) endorse least 7 day UCS values of 1.5 MPa and 1.72 MPa for soils to be used for pavement construction. The ahead of time cracking at interface layer was due to lack of bonding amid layers and hence the samples stabilized with small cement displayed greater inconsistency in the result whereas the sample with greater cement content portrayed lesser difference which was also stated by [3]. It was detected that all soils had a greater amount of loss all through initial cycles which was be likely to drop later.…”

“…[1] Verified clayey soil with and established that increased soaking time causes significant decrease in durability index for initial soaking period of about upto 15 days. [3] Completed durability test on sand and gravel and established that UCS strength has a non-linear power relationship with durability in terms of mass loss % and that increase in W-D cycle results a decrease in mass loss [9] indicated that long testing time of durability tests forces many highway agencies to agree a least 7-day unconfined compressive strength. They established that a minimum seven-day UCS value of 2.2 MPa achieves the durability standards suggested by PCA (1992).…”

The development and growth in economy of the country is primarily depended on the connectivity within the country and region around. The basic and most utilized for of transportation used is the roadways and highways transportation. Good quality metal aggregate is required in large quantity for construction of roads which is scarce in nature. One alternative to this problem is to use the locally available soil by stabilising it with help of cementitious material so that it can be effectively used. The strength and durability are the basic requirements for any stabilised material to be used for road construction and thus in this paper the strength and durability characteristic of 3 soils treated with cement has been tested. The test used for strength evaluation is CBR test & 7 day UCS test and wet-dry durability test has been considered for durability evaluation for cement treated soils. The minimum dosage of cement based on then residual strength and mass loss percent criteria was calculated. It was reported that the amount of cement required for stabilisation is largely depended on the type of soil and vary accordingly.

“…In contrast, in countries having cold weather, durability testing should be conducted against freezing-thawing cycles. The durability of soil has been studied against wetting-drying cycles [61,[73][74][75][76][77][78] and freezingthawing cycles [79].…”

“…However, the durability of some cement-treated soils was also investigated (e.g., [80]), but yet to be investigated vastly. Furthermore, the durability of some stabilized soils has been investigated based on local road standards in other countries [72,74,75], but the durability of cement-lateritic soil has not been investigated yet considering Malaysia Public Works Department (MPWD) standards for low-volume roads.…”

Strength and Durability of Cement-Treated Lateritic Soil

The transportation infrastructure, including low-volume roads in some regions, needs to be constructed on weak ground, implying the necessity of soil stabilization. Untreated and cement-treated lateritic soil for low-volume road suitability were studied based on Malaysian standards. A series of unconfined compressive strength (UCS) tests was performed for four cement doses (3%, 6%, 9%, 12%) for different curing times. According to Malaysian standards, the study suggested 6% cement and 7 days curing time as the optimum cement dosage and curing time, respectively, based on their 0.8 MPa UCS values. The durability test indicated that the specimens treated with 3% cement collapsed directly upon soaking in water. Although the UCS of 6% cement-treated specimens decreased against wetting–drying (WD) cycles, the minimum threshold based on Malaysian standards was still maintained against 15 WD cycles. On the contrary, the durability of specimens treated with 9% and 12% cement represented a UCS increase against WD cycles. FESEM results indicated the formation of calcium aluminate hydrate (CAH), calcium silicate hydrate (CSH), and calcium aluminosilicate hydrate (CASH) as well as shrinking of pore size when untreated soil was mixed with cement. The formation of gels (CAH, CSH, CASH) and decreasing pore size could be clarified by EDX results in which the increase in cement content increased calcium.
