In the construction sector, which is needed for the rapidly increasing world population, the production of strong and safe buildings is given importance. This is achieved as a result of the functionality, durability and economical material production in construction materials. In order to reduce the dead load in buildings, the use of elements made of lightweight concrete is the most appropriate and alternative method. In the current study, lightweight concrete with 4 different mixtures was produced by using 0%, 0.5%, 1.5% and 2.5% powdered sodium salt-based styrene butadiene polymer admixtures (SBPA). The workability effect of the additive on the fresh mixtures was investigated by the flow table test. The 7 and 28 day compressive and flexural strengths of the obtained samples were tested. Density and porosity ratios of the samples were calculated before the 28-day compressive strength test. According to the results, it was observed that the additive material caused a slight decrease in workability. In addition, decreases were observed in mechanical strengths, but when compared with the literature, considering the decrease in density, it was understood that it is in the class of lightweight concreteswith suitable strength. |
