Abstract

This study investigates the strategies for minimising concrete cracking in building structural. The research is mainly focus on find out the factors of concrete cracking and strategies to prevent and reduce concrete cracking. In order to find out the strategies in effect, this research is choosing the place with the most construction work in Malaysia which is Kuala Lumpur as main area for collecting data. This research intends to find out the factor causing the concrete cracking so that people can based on the factors to find out the strategies to prevent and reduce the crack. A convenience sampling method was chosen and the results of the quantitative questionnaire (n=41) were integrated to ensure a more complete understanding of the data. Frequency analysis and mean analysis method was chosen to summarising the data in to group or class for determine the best strategy of minimising concrete cracking. The results showed that most of the respondents claim that external factor is main factor that contribute to concrete cracking on building structure since external factor is uncontrollable factors. Uncontrollable factor like over growth of roots affect the soil condition and causing movement in foundation of building and causing concrete cracking. Most of the respondents believe using prestressed concrete can reduce the chance of concrete cracking in building structure since prestressed concrete can withstand the tension force of concrete to prevent cracking. Therfore, respondents agreed that prestressed concrete is the most important strategy to prevent and reduce concrete cracking in building structure. This research can benefit to the construction industry since the builder can refer the research result to further understanding how does the concrete cracking in building structure to come out with the more suitable strategies to prevent and reduce the concrete cracking in building structure.
