“…There is a small number of studies about the use of wood as a replacement for fine aggregate or mineral additive [23][24]. Numerous studies have shown that waste powders with low pozzolanic activity can be successfully used as mineral admixtures for production of selfcompacting concrete [25][26][27][28][29]. Elinwa et al [24] studied the impact of sawdust ash on the properties of SCC in fresh stated and concluded that adding the sawdust ash reduces workability of concrete, but that the increase of the amount of superplasticizer can achieve a satisfactory workability.…”

The demand of the contemporary society for renewable energy sources lead to the increase of the bio-power plants. Accordingly, the amount of ash generated by burning the biomass is increased, and its disposal becomes a large environmental problem. The paper presents the research of potential use of biomass wood ash as a partial replacement for coal fly ash (10%, 20%, 30% and 40% of mass) in production of self-compacting concrete (SCC). The effects of biomass wood ash on the properties of SCC in fresh and hardened states have been examined, as well as on the properties of durability. Test results indicated that the biomass wood ash slightly reduces the flowability and passing ability of SCC, while its addition enhances the viscosity of SCC and significantly prevents segregation and bleeding. SCCs with the contents of biomass wood ash up to 20% have approximately same mechanical strength as the reference mixture. Biomass wood ash has no negative effect on the resistance of concrete to the action of water under pressure, but a decrease of freeze/thaw resistance with de-icing salt is detected as its contents increases. The addition of biomass wood ash into SCC increases the drying shrinkage in the initial period of drying (up to 14 days), and it is decreased in a later phase.

“…Very encouraging results were obtained when testing the potential of using industrial by-products such as fly ash, ground masonry elements, and flotation tailing, in fabrication of the self compacting concrete (SCC). A mixture of SCC with flotation tailings had the highest density, while the mixture with waste tiles has proven to be excellent in terms of workability in fresh state as compared to other experimental mixtures [2]. One of good examples of sustainable concrete, described by Malešev et al [3], involved the use of fly ash as a replacement for a part of cement, and recycled aggregate as a replacement for natural aggregate.…”

Effects of addition of finely ground CRT glass on the properties of cement paste and mortarThe paper presents test results for the cement paste and mortars, where a part of cement was replaced with finely ground cathode ray tube (CRT) glass. The following mass percentages of cement were replaced with glass: 5%, 10%, 15%, 20% and 35%. Two mortar series, with 5 and 10% of CRT in the total quantity of cement, were prepared. It was established that the presence of glass does not greatly affect the setting time and dimensional stability of the paste. Mortars with 5 and 10% of CRT exhibited better mechanical properties compared to the reference mortar. All mortar series were found to be frost resistant.

Geopolymers are materials made of chain molecules incurred by polymerization of geopolymer binders. geopolymers are defined as a solid and stabile aluminosilicate materials, made of industrial byproducts and liquid solutions. The experimental part of the dissertation, contains the results of physical-mechanical, microscopic and durability properties of geopolymer mortars and concrete based on fly ash. For the purpose of determining the effect of different byproducts on characteristics of geopolymer mixtures, 24 batches of mortar and 8 batches of concrete were made and tested. (converter slag, wood biomass ash, red mud, and waste glass) in the amount of 5% - 100% with different steps of replacement in relation to to the binder mass. The samples of geopolymer mortar and concrete were cured at an ambient temperature According to the test results some recommendations for the possible application of fly ash and other industrial byproducts for making geopolymer mortars and concretes are made. Tested materials might be used as construction building materials and according to their physical-mechanical characteristics and durability properties, they can be alternative solution for the traditional mortar and concrete mixtures.
