Computer Modelling and Analysis of Polymer Composite Concrete Septic Tank

Raji.S.A | Ako T. | Ogbonna C. A. | Popoola.O.H


Abstract: This study entails computer modelling of reprocessed pure water sachet (PWS) polymer composite concrete septic tank using MIDAS GEN engineering software. The project attempts to model a septic tank considering the properties of reprocessed pure water sachet polymer concrete such as modulus of elasticity, thermal coefficient, poisson ratio and damping ratio in order to determine its performance during service life. More than 45 % of ultimate treatment can be accomplished in the septic tank. Based on review of past Laboratory research the compressive strength of reprocessed PWS determined after 7, 14, 21, 28 days of curing in water respectively was observed to increase as the curing days increased. The strength at 10 % PWS of concrete increased from 17.60N/mm2 for 7 days curing age to 21.20 N/mm2 for 28days curing age. The values of the stresses obtained increased with depth of the septic tank under the critical conditions considered. At depth of 1.5m, stress was established as 3.43N/mm2, 4.32N/mm2 4.85N/mm2 when the tank is empty, half-full and full respectively. The stresses obtained using the Midas engineering software was higher as compared with the manual computation.
