Experimental Assessment of Using Micro-Non Air Bubble (MINAB) and Super-Plasticizer on Setting Time and Compressive Strength of Cement Mortar [PDF]

Journal of Structural and Construction Engineering, 2021
One of the latest innovations in nano-technology is the use of Micro-Nano Air Bubbles (MINAB) as a substitute for water in concrete. Using MINAB as a substitute for water used in concrete can be used to improve the properties of concrete.

Rheological properties of mortars prepared with different sands [PDF]

, 2014
YesThe principal aim of this paper is to investigate the effect of sand grading, surface morphology, and content on the rheological properties—that is, yield stress and plastic viscosity—of fresh mortar. Mortars were produced from four different types of

The research progress and Hotspot analysis of polymer cement mortar based on bibliometrics

Frontiers in Materials
Ordinary cement mortar is commonly used in building engineering due to its high strength, affordability, and easy access to raw materials. However, it suffers from high shrinkage and poor impermeability, which result in reduced building service life and ...

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

Tough, Ductile, and Strong Hard‐Soft Cementitious Composite Enabled by Multi‐Material Additive Manufacturing

Advanced Materials, EarlyView.
Drawing inspiration from the layered hard‐soft architecture found in sea sponges, this work establishes a new framework for architected cementitious composites (ACC) through multi‐material additive manufacturing (MMAM) process. The integration of mortar and elastomer phases into layered architectures enables synergistic toughening mechanisms, including
