Control mortar was prepared mixing 450 g of Portland cement, 225 mL of water and 1350 g of natural sand, whereas OFA replacing mortars were prepared replacing part of the cement by ground OFA, with variable water/(cement+OFA) ratios. For studying the influence of OFA on workability of cement mortars, flow table spread (FTS) of mortar cones was measured according to the already reported .
Jun 09, 2010· Rapidhardening hydraulic cement has been used for both concrete repair and new construction, wherever superior durability and rapid strength gain are required. It is blended and packaged into a wide range of highperformance products including nonshrink grout, structural repair mortar, concrete, exterior plaster, and other cementitious products.

ACRYLOK is a highsolid, acrylic polymer latex admixture and bonding agent. This milky white liquid is nonyellowing in Portland cement mortars and concrete. When used as an admixture, ACRYLOK provides increased abrasion, impact and crack resistance, flexural strength, and freeze/thaw tolerance. Permeability is also reduced, providing added protection from chloride intrusion and scaling.
2. A second advantage of plasticizers is the possibility of considerable savings in cement mortar. Adding plasticizers to the concrete solution can save on the amount of cement mortar. If you compare a solution prepared without adding plasticizers and with them, the amount of cement used in the second case will be 1417% less. 3.

Rheological and Mechanical Properties of Mortars Prepared with Natural and Manufactured Sands. The conventional assessment methods for fine aggregate used in Portland cement concrete are mostly based on round natural sand performance in spite of the increasing use of angular manufactured sands.
Mortar Cement is specified in ASTM C 1329 to have a better bond strength, similar to traditional site mixed mortar. This is preferable for exterior masonry and structural masonry making Mortar Cement a better choice for weather resistance through lower permeability of the masonry, and for seismic and load bearing masonry.
