Assessment on the Effect of Using Different Types of Formwork Materials on Building Construction: A Case Study in Benshangul Gumuz Region
Year: 2020
Type: article
Abstract: Concrete is a construction material which is a composition of coarse aggregate, fine aggregate, cement and water. The steps in Concrete production are Proportioning, mixing, placing and curing. Formwork material is a material used in casting process of fresh concrete to give the desired shape and surface. Due to the application of bad form working, a corrective work is required for the concrete surface. This process will require additional time and labor costs. This study intended to assess the effect of using different types of formwork materials on building construction of Benshangul Gumuz region. The general objective of this research is to assess the effect of using different types of formwork materials on different building construction works in Benshangul gumuz region. And the specific objectives are, to assess the materials and methods used for concrete formwork, to assess the major concrete finish quality problems related to form working and to assess formwork materials considering cost. The research follows both qualitative and quantitative approaches. Data was collected by interview and questionnaire and the data was analyzed by using charts and simple statistical formula of arithmetic mean calculation for a frequency distribution. According to the responses 69% of the respondents said that the most available formwork material is timber formwork. And 96% of the respondents agree that the method of form working applying is formwork set up of timber and eucalyptus connected by using nails and wires. Among the concrete quality problems related to form working, misplaced surface was the most rated problem with mean value of 4.7. According to the answer of the respondents, 78.43% said that timber is the cheapest form work material in the zones. The formwork material which permits many times of reuse is steel formwork. These implies even if the initial cost of timber formwork is lower, in long run steel formwork has better advantage in cost due to number of reuse.
