A variety of methods have been developed to
meet the needs in terms of developing technology with the manufacture of
concrete. Chemical admixtures as known to it were put into operation very
seriously in recent decades. Widespread requested using this frequency of use or
misuse of the contribution as a result of the complicated way the two
properties at the same time ensuring the situation arises. However, combined
use of admixtures incompatible with each other can lead to the formation of
unforeseen effects. Chemical admixtures in concrete, in some cases the discrepancy
is cause to lower than expected or desired results to the formation of unwanted
effects. This study investigated the effects of chemical admixtures are
encountered in the production of concrete mortar samples showed the combination
of different rates was sought to remedy these problems. The chemical admixtures
for mortar components were kept constant at four different combinations
(plasticizer, accelerator, retarder and air entraining agent). Optimal and high
dosage to the samples occur in mixtures prepared fresh and hardened state
experiments by applying flow-test, viscosity, setting time, fresh and hardened
unit weight, ultrasonic pulse velocity, compressive strength, flexural
strength, apparent porosity were investigated and micro-structure analysis were
performed. The results obtained from this study contribute to a model showing
the effects of using artificial neural networks have been trying to develop.
Within a short time results that can be aimed to prevent loss of time in this
type of work with this method.
