A microstructural approach to adherence mechanism of cement and asphalt mortar (CA mortar) to repair materials

Construction and Building Materials, 2014
Abstract Cement and asphalt mortar (CA mortar) is the key component for high-speed railway with high asphalt content to obtain low modulus which makes it difficult to bond with repair materials. The purpose of this work was to investigate the bonding mechanism of CA mortar to two type repair materials – SAC-AE composite mortar (short for SACR) and ...

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
