In response to the high carbon emissions and energy consumption of traditional cement curing agents, in this paper, we propose a fly ash/slag-based geopolymer as an alternative for stabilizing soft soils. study, effects activator modulus, activator, slag content on geopolymer-stabilized clay were investigated by unconfined compressive strength (UCS) tests Hangzhou soils, water stability resista...

Healing of corneal alkali injuries remains a severe clinical challenge. The authors evaluated the effect of a new synthetic inhibitor of matrix metalloproteinases (GM6001 or N-[2(R)-2-(hydroxamido carbonylmethyl)-4-methylpentanoyl]-L-tryptophane methylamide) on preventing ulceration of rabbit corneas after alkali injury. Topical treatment of corneas with severe alkali injuries with 400 microgra...

We report methodological advances that enhance the phosphorescence efficiency of a blue-emitting calcium aluminate phosphor (CaAl2O4: Eu2+, Nd3+). The investigation of long-persistence blue-emitting phosphors is highly desirable due to their promising applications, such as white LEDs; however, the development of highly efficient blue-emitting phosphors is still challenging. Here, we have quanti...

In recent years, the utilization of different non-traditional cements and composites has been increasing. Alkali-activated cementitious materials, especially those based on the alkali activation of blast furnace slag, have considerable potential for utilization in the building industry. However, alkali-slag cements exhibit very rapid setting times, which are too short in some circumstances, and...

To reduce the antagonistic effect of jute fibre on the setting and hydration of jute reinforced cement, modified jute fibre reinforcement would be a unique approach. The present investigation deals with the effectiveness of mild alkali treated (0.5%) jute fibre on the setting and hydration behaviour of cement. Setting time measurement, hydration test and analytical characterizations of the hard...

Nanomaterial which has high activity is widely used in the modification of cement-based materials due to its physical filling and chemical bonding. This paper mainly studied the influence of nano-SiO2 on the compressive strength of the alkali-activated materials, using XRD and SEM technology to analyze the mineral composition microstructure of alkali-activated materials, modification effect, et...

Abstract The resistance of alkali-activated materials (AAMs) to degradation processes, particularly the decalcification, was studied in this paper. ground granulated blast furnace slag using various activators with same activator dosage 6% Na 2 O by weight (sodium hydroxide, sodium waterglass and carbonate) subjected testing decalcification (immersion 6M NH 4 NO 3 ) for 84 days. reference sampl...

The effects of using recycled concrete aggregate (RCA) as coarse on the equivalent substrate stiffness and mechanical properties sustainable alkali-activated were investigated in this paper. High-calcium fly ash (HFA) commercial silica fume (SF) used precursors for producing high-calcium (AAHFAC). Sodium hydroxide (SH) sodium silicate (SS) solutions alkaline activator with constant SS/SH ratio ...
