Experimental Study of Conplast SP430 in Concrete Using
problem among the users about what type of super plasticizers to be used with what type of cement and what optimum dosage of super –plasticizer should be added. Consequently, this study involves the application of Conplast SP 430 Superplasticizer on three different cement brands in northern part of Nigeria. The same Grade

Comparison and Optimization of Dosage of Different Super
The use of Super plasticizer is practiced for production of flowing, self-leveling and self-compacting for the production of high strength and high performance concrete. They are called High Range Water Reducers (HRWR) in American literature. It is the use of Super plasticizer which has made it possible to use w/c as low as 0.25 or even lower

the same. The job of SP-430 is to impart a high degree of flow ability and deformability, however high dosages can lead to a high degree of segregation (Ramchandran, and Malhotra). Conplast SP 430 is utilized in this project, which is a product of FOSROC (Manufactured at Bangalore, India) having a specific gravity of 1.22.
- Does conplast SP 430 super plasticizer reduce water absorption?
- The results showed that all the concrete mixes with presences Conplast SP 430 super plasticizer exhibited improvement in compressive strength andnoticeable reduction in water absorption compared to their control mixes.
- Can conplast SP 430 superplasticizer be used on different cement brands?
- Consequently, this study involves the application of Conplast SP 430 Superplasticizer on three different cement brands in northern part of Nigeria. The same Grade 42.5N of the three cements were selected and coded as NB, ND, and NS respectively.
- Does conplast SP430 increase compressive strength?
- The compressive strength results of the concrete with Conplast SP430 content is in conformity with finding of Elinwa , which indicated anincrease in strength. Although, there was no appreciable strength gain at early age when compared with control for all the three type of cement.
