Development of grout for additional seal embankment dams
(Elsevier, 2015-06-25)The technology of sealing sand and gravel by chemical injection has been known and used for a long time. Chemical grouting is however expensive and sometimes the use of cement does not lead to the desired effect. That is ... -
Solidification of Hazardous Waste with the Aim of Material Utilization of Solidification Products
(Elsevier, 2015-07-09)This work deals with the possibility of using solidification technology to transform the hazardous waste with the aim to achieve the material utilization of solidification products. For this purpose, it is necessary to ... -
Development of microstructure of the fly ash aerated concrete in time
(Elsevier, 2015-07-09)Calciumhydrosilicate components formed during autoclaving process are highly complex formations, which often blend together mutually and form a variety of intermediate products, from completely amorphous, to the good ... -
Technology of Remediation of Embankment Dams by Optimal Grout
(Elsevier, 2016-05-31)Floods represent one of the greatest direct dangers of natural disasters in Europe. During floods, substantial material damage and often even losses of human life may occur. In the Czech Republic both of these were recorded ... -
