Sustainable cement mortars [PDF]
E3S Web of Conferences, 2018 The results described here on the basic technical parameters of cement mortars made from fine-grained concrete recyclate, ceramic recyclate, and slag, obtained from the incineration of municipal sewage sludge, demonstrate their usefulness in the production of building materials. Changes were introduced to the composition of cement mortars involving the

Characterization of Sulphoaluminate Cement-Asphalt Emulsion Mortar for Cement and Asphalt Mortar Repair [PDF]
Frontiers in Materials, 2020 A sulpho cement-asphalt emulsion mortar was developed for the repair of damaged cement asphalt emulsion mortar. Various sulfoaluminate/Portland cement and asphalt emulsion/cement mass ratios, as well as emulsion types, were studied with respect to the setting time, rheological properties, volume stability, and mechanical properties of the repair ...

Efflorescence of Cement Mortar
Journal of the Ceramic Association, Japan, 1960 セメントとモルタルの配合に関する各種要因がエフロレセンスとこれに関連ある特性におよぼす影響について調べた. エフロレセンスはセメント中のアルカリ量を減じ, またモルタルを緻密にすることによって軽減される. モルタルの吸水, 乾燥および透水の速度は主として水セメント比が低く, 水和度の高いことによって減少する. したがってモルタルを緻密にするために粗目の砂を用い, 添加材として高炉水砕スラグの微粉末を一部セメントに置換して加えることはエフロレンス防止の面でも有効と思われる. ただしモルタルを富配合にすることは同時にアルカリ含有量を高めることになり明らかな効果をもたらさなかった.

, 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 ...

Properties of cement–lime mortars vs. cement mortars containing recycled concrete aggregates
Construction and Building Materials, 2015 Abstract Cement based materials have a very special presence amongst building and construction materials, and therefore their recycling is of capital importance. In this research, concrete wastes were used as replacement of natural aggregates in cement and cement–lime mortars. The mortars were cured for 28-days with an increasing substitution of fine

, 1964 Many important properties of masonry, particularly strength and weather resistance, are affected to a considerable degree by the type of mortar used. One type, generally known as cement-lime mortar, is used extensively in North America and Europe for all types of unit masonry construction.
