A Study on the Mixture Ratio of Pumice Powder Concrete on the Concrete Pavement and the Construction of Building

Abstract

Pumices which have substantially the reserve in the region of Bitlis and are known with the name of “bims” are the robust extrusive rocks against the aerated, spongy, physical and chemical factors which occurred when the extrusive lavas which occurred with the explosion of crater Nemrut in the region in the past expanded and cooled. As the pumice with the pore substantially at the macro and micro sizes has a very low compressive strength, its usage field has been restricted in the sector of construction, and it is mainly used in the construction of wall and par get in the purpose of insulation. As the pumice aggregate has a very low compressive strength, it isn’t used as the construction concrete in the bearing parts of buildings. This is why the pumice aggregate which is used in the concrete has the high-amount gaps. The compressive and bending strength of concrete which will be done by grinding the bulky pumice aggregate and making it powder can be increased. The concrete which was done in this way was named as Pumice Powder Concrete (PPC). This study was prepared in order to provide the common usage of PPC in the sector of construction, to contribute to the regional and national economy with widening the pumice’s usage fields in this way. The mixture ratios at the different water/binder ratios of Pumice Powder Concrete (PPC) were obtained for the rigid pavement and the construction of building in this study. PPC mixtures were done in two ways as the fibrous and non-fibrous ones. In the study, the mixture ratios were done as 0.20-0.30-0.40 and 0.50 of the fibrous and non-fibrous PPC mixtures’ water/binder ratios, and they were shown on the tables.
