Problems relating to disposal of sludge accumulating at waste-water treatment plants (WWTP) in Croatia are described in the paper. The possibility and adequacy of using ash obtained through incineration of sludge is considered. A special emphasis is placed on the significance of ash in concrete industry during production of cement mortar and concrete. Results of worldwide research conducted so ...

Sustainability and the UK cement industry Traditional Portland cement-based concrete provides the foundation for the built environment. Buildings constructed appropriately and imaginatively from this material can and do exhibit an impressive array of properties [1] especially those that have been designed to optimise the thermal mass of concrete [2]. This type of concrete building is expected t...

Aquaculture is among the oldest occupations of human being. Over the past quarter of century, the aquaculture industry has grown rapidly. The effect of water containing sodium sulfate on long term compressive strength of concrete of fishing ponds and channels is investigated in this paper. Aim of this paper was to analyze the strength of concrete channels and of aquaculture which are in direct ...

in spite of the fact that cementitious and concrete materials are mainly used on a large scale and inhuge quantities for roads, dams, bridges and building constructions, the mechanical behavior of thesematerials depends to a great extend on structural elements and phenomena which are effective on amicro and nanoscale. although this is well known by researchers, material producers and engineersf...

As the premier material in construction industry across the world, concrete has major role in the effects of construction to our environment. Consumption of concrete is very high due to extensive use of concrete in many structural applications. The rapid infrastructural growth in developing countries and production of many by-product as waste material making high role to concrete producers in i...

The construction industry generates a considerable amount of waste. Faced with this undesirable situation, the ready-mix concrete sector, in particular, has invested energy and resources into reusing its own waste in its production process as it works towards the goal of more sustainable construction. This study examines the feasibility of incorporating two types of concrete waste, which curren...

The susceptibility of structural concrete to early-age cracking depends on material composition, methods of processing, structural boundary conditions, and a variety of environmental factors. Computational modeling offers a means for identifying primary factors and strategies for reducing cracking potential. Herein, lattice models are shown to be adept at simulating the thermal-hygral-mechanica...
