Behaviour of Ca(OH)2 in polymer modified mortars

Cement and Concrete Composites, 1989
This paper deals with the effect of polymer modification on the behaviour of calcium hydroxide in modified mortars. The polymer modified mortars were prepared using powdered emulsions and aqueous polymer dispersions at various polymer-cement ratios; they were then tested for air content, moulded into specimens and cured. The cured specimens were tested

Deterioration of CA mortar filling layer under cyclical thermal loading

Construction and Building Materials, 2020
Abstract Cement and emulsified asphalt mortar (CA mortar) has been widely used as a filling layer between concrete bed plates and track slabs for high-speed railways. This study analyses the cracking mechanism of the interface between CA mortar and the concrete under CT treatment (cyclical temperature from −40 °C to 60 °C) and CTI treatment (cyclical
