An investigation of laterite as fine aggregate to develop eco-friendly mortar

Develop Eco-Friendly Enterprise: Aligning Enablers with Strategy

Environmental friendliness has been regarded as a fundamental characteristic of sustainability and competitiveness, yet such eco-friendliness is often not performed well. Based on the relationship matrix in the Quality Function Deployment (QFD) method and fuzzy logic, this paper presents an original integrated approach that, by linking competitive bases, green capabilities, and providers, aims ...

Properties of Cement Mortar by Use of Hot-Melt Polyamides as Substitute for Fine Aggregate

This paper presents an experimental study on use of hot-melt polyamide (HMP) to prepare mortar specimens with improved crack healing and engineering properties. The role of HMP in the crack repairing of cement mortar subjected to several rounds of heat treatment was investigated. Compatibility between HMP and hydraulic cement was investigated through X-ray diffraction (XRD) and Fourier transfor...

An Eco-friendly Route to Synthesis of Quinolines

Some 2-hydroxy-4-methyl-6substituted quinoline derivatives have been synthesized in an environmentally benign method from easily available 4-substituted anilines and β-Ketoesters, under ordinary conditions. The reactions were catalyzed by aluminium chloride to afford excellent amount of the products. The usage of hazardous acids, bases and solvents have been avoided in different steps of the re...

Green Synthesis of N-pyrroles in Water via Using ZrOCl2.8H2O as an Efficient and Eco-Friendly Catalyst

A simple and efficient protocol for the synthesis of N-substituted pyrroles from one-pot condensation reaction of 2, 5-dimethoxytetrahydrofuran with aryl/alkyl, sulfonyl and acyl amines in the presence of ZrOCl2•8H2O in water has been developed. This new method has the advantages of simple experimental and work-up procedure, high to excellent yields, easy availability, economical, eco-frien...
