- ItemInvestigating the Effects of Formwork Material and Thickness on The Early Strength of Concrete.(Kabale University, 2023) Natukunda, BenjaminThe materials considered in this project were steel and timber, which are the most used materials for formwork. The thicknesses for steel used were 2mm, 6mm, and 8mm while thicknesses for timber were 15mm, 25mm and 35mm. The concrete from the same mix design was cast in the different moulds and left to stay in the moulds for the required number of days at which the compressive tests were done. That is at 1 day, 3 days and 7 days for which are the early ages of concrete. The investigation involved material classification tests, fresh concrete tests (slump test) and hardened concrete tests (dry density and compressive strength) The investigation found that after the strength development of concrete cast in the steel form work was higher than the strength of concrete cast in the timber formwork. This was because the concrete cast in the steel formwork had a higher compressive strength after 7 days with the 8mm thick mould giving the highest thickness of 16.61 MPa compared to the highest strength by concrete in the 25mm thick moulds 15.49MPa. For the steel formwork, from the results, compressive strength results from a thicker steel formwork were higher than compressive strength results from a thinner steel formwork For the timber Formwork, from the results, compressive strength results from the 25mm thick moulds were higher than the compressive strength results from both the 15mm and 35 mm thick moulds
