Materials For Construction - Essay Example

The main differences occur in the mixtures that were made and used in the construction of the structures. For structure A, a water concrete ratio of o.4 has been applied while for structure B, a water concrete ratio of 0.45 is applied. Structure B applied a higher ratio of water to cement than structure A. This indicates that structure B will be stronger than structure A. In structure B 8% of silica fume is applied. Silica fume enhances the strength and durability of the concrete (Yudelson, Jerry). The concrete used for structure B is, therefore highly durable. For structure A, 30% fly ash was mixed with the cement. This may not add as much durability as compared to the addition of silica fume. For structure, A epoxy coated rebar is used at 5% volume for reinforcement while structure B applies black steel rebar at 4%. For reinforcement, we can therefore say that structure A is better than structure B. structure A has used 15.5 liters of inhibitor-free while structure B has used 10 liters. This indicates that structure A is more protected from corrosion effects than structure B.

According to the results provided, the cost of both structures will be increasing as time goes on but the rate of increase for structure A will be a bit higher than that of structure B. the results indicate that the location of structure A is more stable than that of structure B.
