Abstract: This study examined the effect/impact of corrosion inhibitors on flexural strength of failure load, midspan deflection, tensile strength and elongation of steel reinforcement layered with resins/exudates of magnifera indica extracts as corrosion inhibitors. Steel reinforcement were coated with 150µm, 250µm and 350µm of magnifera indica resins/ exudates paste, embedded in concrete beam members and exposed to harsh and saline environment (Sodium Chloride) Nacl. Corrosion acceleration process was initiated for 90 day to determine corrosion possibility. Results obtained showed corrosion potential on uncoated concrete beam members. More results recorded on experimental work showed flexural strength failure load, midspan deflection, tensile strength and elongation as 29.09%,31.20%, 11.75% and 31.50% for non-corroded, 29.42%, 27.43%, 12.09% and 31.60% for coated concrete beam respectively. For corroded concrete beam members, failure load decreased to 22.505, midspan deflection increased by 39.30%, tensile strength decreased to 10.17% while elongation increased by 46.30%. Entire results showed the effect of corrosion on the flexural strength of reinforcement that led to low load on failure load and higher midspan deflection on corroded beams and hiher load on failure load and low midspan deflection on non-corroded and coated concrete beam members resulting to attack on surface condition of reinforcement from corrosion.

Abstract: The main purpose of the study was to establish the role of project planning on effective implementation of real estate construction projects in Kajiado County, Kenya. The study employed descriptive research design since it minimizes biasness. The study focused on five on-going projects from each of the 52 registered real estate construction firms in Kajiado County. Therefore, the target population was 260. The unit of observation was the real estate project managers and project supervisors. The study used 20% of the target population and thus the sample size was 104 respondents. This study used primary data which was collected using questionnaires for the real estate construction projects. Simple random sampling was used to sample the project managers and project supervisors. The research instruments were validated by use of a pilot study, which was assessed by the supervisor. Data collected was analyzed by use of Statistical Package for Social Sciences (SPSS) Computer Package version 22 to produce frequencies, descriptive and inferential statistics which were used to derive conclusions and generalizations regarding the population. A multiple regression model was used to show the relationship between the independent variables to the dependent variable. The study found that project planning had a positive and significant effect on the effective implementation of real estate construction projects in Kajiado County. The study concludes that effective project planning leads to improvement in effective implementation of real estate Construction projects. Project teams therefore, should be highly competent to engage highly on reputable projects to bring about good project outcomes as a result of effective project planning.

Keywords: project planning, of real estate construction projects, produce frequencies.
