Effect of Time Period between Mixing and Application of Cement Mortar on Compressive Strength
Journal of Engineering and Sustainable Development, 2013 This paper investigates the effects of time period between mixing and application of cement mortar on compressive strength. Two groups with a total of (135) cubes were cast and tested at 28 days age.

Numerical analysis of debonding behavior of FRP sheets bonded to concrete focusing on mortar skin
Structural Concrete, EarlyView.Abstract This paper proposes a novel simple method for finite element analysis (FEA) to simulate the debonding behavior of fiber‐reinforced polymer (FRP) sheets bonded to concrete. This study focuses on the mortar skin of the concrete surface layer, which fails during FRP sheet debonding.

Petrography of Potentially Alkali Reactive Sandstone from Argentina [PDF]
, 2012 Petrographic characteristics of sandstone from the Province of Corrientes, Argentina, were studied. The rock has been classified as potentially alkali reactive in previous work using the accelerated mortar bar test method (ASTM C 1260).

Pre‐failure behavior of continuous post‐tensioned and post‐grouted beam in case of tendon failure
Structural Concrete, EarlyView.Abstract Grouted tendons are a common solution for long‐span bridge structures. The grout provides bond and corrosion protection for prestressing steel. However, if the grouting is defective, corrosion of the prestressing steel may initiate and eventually lead to tendon failure.

, 1970 Masonry mortars are assessed on the basis of tests on specimens prepared and cured in the laboratory. Curing procedures differ depending on the relative amounts of cement and lime in the mortar, and the relation between the end result and that attained in the field, where no concession is made for the composition of the mortar, is often questioned ...
