ABSTRACT
In this
research study, a mathematical model is developed to optimize the
palm-net-fiber reinforced concrete’s compressive and flexural strength using
Scheffe’s (5.2) simplex-lattice design, palm – nut – fiber which is an
agricultural residue obtained after the processing of palm – oil is utilized as
the fifth component in concrete consisting of water, cement, fine and coarse
aggregates. Fibers are used to help fresh concrete to keep it from cracking and
plastic shrinkage and also for a concrete structure of complicated or complex
geometry where obtained for the different componential ratios using Scheffe’s
Simplex method and for the control points which will be utilized for the
validation of the Scheffe’s model. The model’s adequacy was tested using student’s
t-test and ANOVA at 5% critical value. The statistical result indicates a good
relationship between the value obtained from developed Scheffe’s model and the
control laboratory results. The maximum value of compressive strength of the
palm-nut-fiber concrete obtained was 31.53mm2 corresponding to mix
ratio of 0.525:1,0,1,45;1.75:0,6 and minimum value of compressive strength
obtained was found to be 17.25Nmm2 corresponding to mix ratio of
0.525:1.0:1.8:2.5;12; an optimum compressive strength of 11.40Nmm2
corresponding to mix ratio of 0.6:1.0:2.0.2.8:1.1. for water, cement, fine and
coarse aggregate and palm-nut-fiber respectively. Using the developed Scheffe’s
Simplex Model, the proportion of the mixture ingredients to a certain
prescribed compressive strength value can be estimated with a high degree of
accuracy and also providing the solution in less amount of time.
