Lime mortars doped with graphene nanoplatelets

Original language description

The aim of the presented study is to investigate the influence of the edition of graphene nanoplatelets (GNs) on properties of lime-based mortars. The mortars containing 0.5 wt.% and 1.0 wt.% of nano-additive were prepared with two-step mixing method, which included dispersion of graphene in part of mixing water using mechanical homogenizer and mixing of all components with planetary-type mixer. Chemical composition of used binder and aggregate were investigated using X-ray fluorescence technique (XRF). For fresh and hardened samples, workability, structural, mechanical, and water vapor characteristics were studied. Workability of fresh mortars was characterized by flow table test. Bulk density, specific density, and total open porosity were the assessed structural properties of hardened mortars. The analyzed mechanical parameters were flexural strength, compressive strength, and dynamic modulus of elasticity. Among water vapor transmission characteristics, water vapor resistance, water vapor permeability, and water vapor resistance factor were evaluated using a dry-cup method based on 1-D water vapor transmission test. The addition of GNs led to the minor changes of basic structural characteristics and other properties related to the total open porosity of material. Despite these small changes, the mechanical resistance of mortars significantly increased. The compressive strength was of about 12% higher when 1.0 wt.% of GNs was applied. Based on the conducted experimental analyzes the developed lime-based mortars with GNs additive show potential for further improvement of mixture composition. Change of water/binder ratio, application of other type of nanomaterial with different particle size and specific surface or use of higher volume of nanoadditive might be beneficial for overall performance of this type of materials and will be investigated in a near future.
