THE EFFECTS OF ADDITIVES ON THE PROPERTIES OF BRICKCLAY PRODUCTS
The effect of fly ash, coal dust and limestone on the properties of brick products are presented in this paper. Three kinds of clay were used to test the effect of additives. There were investigated the effect of additives on the behaviour of clays during drying and firing (shrinkage and loss of weight), and the properties of fired samp...

A REVIEW OF THE METHODS FOR PROPORTIONING SELF-COMPACTING CONCRETE
For the production of self-compacting concrete for a specific application, with desired properties in fresh and hardened state, it is necessary to combine the constituent materials in the optimum proportions. The proportioning of self-compacting concrete has to start with defining the required properties. For a particular application, a self-compac...

THE EFFECT OF DIFFERENT TYPES OF FLY ASH ON SELFCOMPACTING CONCRETE PROPERTIES
In this paper the effect of two different fly ash types on the properties of self-compacting concrete in fresh state and hardened state was investigated: fly ash from Thermal power plant “Kakanj” and fly ash from Thermal power plant “Tuzla”. The results of testing fresh self-compacting concrete properties show that addition ...

AN OVERVIEW OF PORE FORMING ADDITIVES USAGE IN FIRED CLAY BRICKS
For the production of vertically perforated bricks with very good thermal insulation properties it is necessary to increase porosity of ceramic body. The most effective way to achieve this is the addition of organic substances into the clay mass. During the firing process combustion of these substances occures, leaving behind a large number of fine...

EFFECT OF ADDITION OF COAL FROM COAL MINE “KAKANJ” ON PROPERTIES OF BRICK CLAY “RAPAJLO”
A coal dust is added to brick clay mainly to save energy and increase porosity. This paper examines the influence of coal from Coal mine "Kakanj", in the amount of 10% and 20%, on some physical and technological properties of brick clay "Rapajlo". The impact of coal on the plasticity of clay, and the characteristics of dried and fired samples was i...

USE OF RECYCLED AGGREGATE IN CONCRETE
In order to determine the possibility of using recycled aggregate for concrete production, properties of recycled aggregate and limestone aggregates: particle size distribution, oven-dried particle density, saturated and surface dried particle density and apparent particle density, water absorption, resistance to fragmentation and impact resistance...
