A fiber glass -silica fume and silica (SF) mix (F-SF) have been employed in this study order to enhance relate their effects on the expansive soil. Bentonite (B) was added with natural soil a lab at ratio of 50% by dry weight create used study. The alone (8,9,10,11,12, 13) % 1 Fiber (F) (clay - SF) mixture. For both treated untreated soil, odometer, shear box, swelling tests were examine behavior after addition From outcome experimental tests, we noticed that reducing comparison index (Cc), reloading (Cr), percentage (SW)%. Also, it is influenced strength parameters decreasing cohesion (c) increasing internal angle friction (φ). As well as adding mixture modify prepared (SW) (c, φ). Based all above results, concluded mix. can engineering characteristics

This study investigates the durability under wetting and drying conditions of marginal lateritic soil (MLS) stabilized with a one-part high-calcium fly ash geopolymer (OPFAG). The variables include an MLS: ratio 70:30, solid sodium hydroxide content ranging from 0 to 40%, number wet-dry cycles. Durability is evaluated by measuring unconfined compressive strength (UCS) MLS samples OPFAG ordinary Portland cement (OPC). results show that improved engineering properties MLS. highest UCS values are achieved at 20% hydroxide, achieving 1889 kPa for geopolymer-stabilized 5% OPC OPC-stabilized (1320 kPa). both increases cycles up 6 cycles, after which decline observed.
