Experimental Study on Improving Frost Resistance of Ca Mortar

Materials Science Forum, 2022
Cement asphalt mortar (CA mortar) is one of the key materials of slab ballastless track structure, and its performance directly affects the overall quality of ballastless track. The design of CA mortar mix proportion is studied by orthogonal exerimental method, and the reasonable dosage of cement, emulsified asphalt, sand and other materials is ...

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

Bonding Durability of Two Repair Mortars with Low Modulus Cement and Asphalt Mortar (CA Mortar)

Journal of Testing and Evaluation, 2017
Abstract This paper presents the results of a study investigating the bonding performance of two type repair materials, resin mortar (RM) and sulphoaluminate cement-asphalt emulsion mortar (SACR), with substrate cement and asphalt mortar (CA mortar) when repair systems are subjected to freezing-thawing cycles and thermal shock.
