The study focuses on the properties assessment and application of regression analysis compressive strength hollow sandcrete blocks. A total ten (10) block producers were visited fine aggregates used in production collected, a number 10 blocks per producer was collected with curing period 7 days transported to laboratory civil environmental engineering, Air force institute technology Kaduna, where it further cured for an additional making 14 days. test carried out includes: sieve analysis, dimension test. mix composition each also determined. Modelling using Minitab software carryout multiple develop model terms constituent materials age result obtained from sand various revealed that by do not comply specified standard grading aggregates, proportion selected does required ratio dimension, average ranged 0.24 N/mm2 0.35 N/mm2. generated gave coefficient (R2) 0.901 block, showing good correlation.
