Resistance to biogenic sulphuric acid corrosion of polymer-modified mortars
The use of polymer-modified mortar and concrete (PMM and PMC) is investigated to improve the durability of concrete sewer pipes. The aim of the research is to ameliorate the resistance of concrete to biogenic sulphuric acid attack through polymer modification. Prior to the durability tests, experime[r]

Microstructures and mechanical properties of polymer modified mortars under distinct mechanisms
In this study, two types of acrylic latexes, PA (polyacrylate) and PU/PA (polyurethane modified PA), are investigated in their influences on mechanical properties of mortar under different interaction mechanisms. In light of a previous study, the polymer–cement hydrates interaction mechanisms in PA[r]

EMPIRICAL MODELS OF CORROSION RATE PREDICTION OF STEEL IN REINFORCED CONCRETE STRUCTURES
This study shows several empirical models to predict the corrosion rate and their limits of application. The predicted values of steel corrosion rate using four empirical models are compared with the measured values of a series of 55 experimental samples collected from the literature. The results sh[r]

Changes in microstructures and physical properties of polymer-modified mortars during wet storage
The decrease in strength of tile adhesive mortars during wet storage was investigated. In a first approach, the water resistance of the polymer phases was tested on structures isolated from the mortar and in situ. It was observed that cellulose ether and polyvinyl alcohol structures are water-solubl[r]

Mechanical behavior of cement mortar with different polymer type
Mechanical property of cement mortar is closely related to polymer modifier type. Four kinds of polymer latex including Chloroprene Rubber (CR), Styrene Butadiene (SBR), Styrene Acrylic (SA) and Polyvinyl Acetate (PVAc) were selected to prepare the modified cement mortar in this study.
