THE INFLUENCE OF VISCOSITY MODIFYING ADMIXTURE ON THE SHRINKAGE OF PLASTERING MORTARS
Journal Title: Structure and Environment - Year 2017, Vol 0, Issue 4
Abstract
This paper presents the influence of viscosity modifying admixture on the shrinkage size of plastering mortars. The composition of cement and cement-lime mortars has been modified by the use of cellulose ethers polymer admixture of various viscosity. Shrinkage tests were performed using the Graf-Kaufman apparatus. Shrinkage deformation analysis was supplemented with chosen properties of pastes and mortars in the plastic and hardened state. The beneficial effect of cellulose ether admixture on the reduction of plastering mortars’ shrinkage strains was found.

THE USE OF THE FRACTAL GEOMETRY TO DESCRIBE THE PORE SPACE IN WET SOURCE CLAYS
In this paper the authors attempted to use the fractal geometry to describe the pore space of the water-clay systems. The analysis was carried out on the source clays STx-1b and SWy-2. The values of the constant paramete...
EFFECT OF SEWAGE SLUDGE DIGESTION ON THE MOBILITY OF HEAVY METALS ON THE EXAMPLE OF THE WASTEWATER TREATMENT PLANT IN SITKÓWKA-NOWINY
In sewage sludge, heavy metals can be dissolved, precipitated, co-precipitated with metal oxides, adsorbed or associated on particles of biological residue. Heavy metals come as oxides, hydroxides, sulphides, sulphates,...
FATIGUE LIFE COMPARISON OF RECYCLED COLD MIXES WITH DIFERENT TYPE OF BITUMEN BINDER
loading cycles. The possibility of using foamed bitumen and bitumen emulsion as binders in the composition of road bases makes it necessary to identify the influence of the binder type on the service life of these layers...
