Properties of Mortars Produced with PKF Press Filter Waste
The limestone is used in different stages of the sugar industry. In a phase of the sugar manufacturing process, limestone, approximately 36 h after loading the top of a limestone quarry, which is cylindrically shaped with lime coke is taken as the bottom of a limestone quarry. Lime obtained by quenching hot water, is filtered and used in the production slurry treatment. At given temperature, the raw juice obtained from sugar beet lime is mixed in the apparatus. Some of the muddy slurry of mud here is precipitated in the decanter. The precipitated sludge is filtered by means of filter presses portions. This land including 70–80% dry material is called “PKF press filter waste soil”. The effect of the waste material referred as PKF press filter waste soil that is used rather than cement in mortar mixture by weight of cement in different ratios have been investigated on mortar properties. In the scope of this aim, the results obtained from the experiments carried out with reference mortar produced in laboratories and compressive strength values are compared with mortar samples containing waste material. Cement weight of waste, PKF waste used in the mixture of 5, 10, 15, 20% sand, water and CEM I 42.5, CEM II 32.5 type of cement were obtained from mortar mixture and was poured into prismatic molds with in size 4 × 4 × 16 cm and 2 in size 4 × 4 × 8 cm samples were prepared. Samples are over 7 and 28-day compressive strength tests were performed. 5% by weight of the cement that is used PKF waste in mortar samples 7-day average compressive strength is determined as 29.25 MPa for CEM I 42.5. These strength values; in the framework of the ongoing research process of mortars, have been shown to have the appropriate standards.
