Behaviour of cement composites with lightweight and heavyweight aggregates at high temperatures
(Budapest University of Technology and Economics, 2017-03-24)
This paper presents new results of the research of the influence
of individual input components done on the behaviour of cement
based composite materials exposed to high temperatures. A
new approach of this research lies ...
Verification of the Possibility of Solidification Product Made of Neutralization Sludge use in the Building Industry
(Elsevier, 2013-05-16)
This paper deals with hazardous waste solidification /stabilisation, specifically neutralization sludge that comes from active industrial sources and neutralization sludge that comes from old ecological sources. As ...
Composites Based on Alternative Raw Materials at High Temperature Conditions
(Budapest University of Technology and Economics, 2017-10-24)
This paper presents newly developed polymer-cement composites. The primary binder (cement) was partially substituted by use of blast-furnace slag and high-temperature fly ash. A lightweight aggregate – agloporite (grain ...
Techniques of Soil Modification for Re-use in Construction
(IOP Publishing, 2018-07-16)
Nowadays effort is made to study what effects may impact the environment and to address the issue of waste management. The majority of all waste produced is construction waste and demolition debris (approx. 65%). This ...
Repairing composite using hazardous waste containing heavy metals
(IOP Publishing, 2018-07-16)
This research deals with the possibility of using hazardous waste in epoxy resinbased polymeric substances. More specifically, it is the use of neutralising galvanic sludge (NGS), which produces as a by-product in the ...
Monitoring the long-term durability and microstructure of polymer concrete patching materials with high content of secondary raw materials using advanced methods
(IOP Publishing, 2018-07-16)
For commercially produced polymer systems, only primary raw materials are used
as fillers. These fillers are predominantly pure silica sand of various grading. The substitution
of primary materials with secondary raw ...
Methods of testing the properties of fibre-cement composites
(IOP Publishing, 2018-07-16)
The paper deals with process of manufacturing the fibre-cement materials and methods of testing their climatic performance. Basic raw materials for production fibre-cement sheets are cement, cellulose fibers, reinforcing ...
Study of hydration process of ternesite clinker
(IOP Publishing, 2018-07-16)
Currently ternesite, Ca5(SiO4)2SO4, is used in the cement production, is one of two
key phases of calcium sulfoaluminate cement. Some investigators claim that this phase is nearly inert or very low reactive and it hydrates ...
Effect of wood chips properties on mineralogical composition and microstructure of silicate matrix based composites
(IOP Publishing, 2018-07-16)
The research presented in this article was focused on proving the effect of wood chips parameters on the hardening process of silicate matrix in cement-bonded particleboard. Namely content of humidity in the chips (in range ...
Usability of alternative admixtures for the production of blended cements
(IOP Publishing, 2018-07-16)
This paper studies how pozzolan materials can be mechanically activated. For this, two major grinding technologies and different types of artificial pozzolans, such as red brick dust, granulated blastfurnace slag and sheet ...
