Characteristics of Stone-Base Laterized Concretes

Stone-base, a material often used for base construction in flexible pavements, have recent studies been shown to be suitable as an all – concreting aggregate. This study investigated the crushing, flexural and split tensile strengths well other mechanical properties of stone-base laterized concretes (SBLC). Normal river sand fine aggregate was partially replaced by laterite while coarse proportion made stone base. Concrete mixes containing 100%, 75%, 50%, 25% 0% replacement (by weight) with were prepared. The workability fresh concrete determined using slump test. Observed slumps ranged between 20 70mm maximum crushing strength 23.6N/mm2 produced specimen 75% sand. All increased age curing quite comparable that control which stood at 25.1N/mm2. A density 2329kg/m3 recorded 28 days curing. showed stone-based are normal weight can purposes.
