Experimental Study on Replacement of Fine Aggregate by Quarry Waste and Partial Replacement of Cement by Artificial Pozzolans.

INTERNATIONAL JOURNAL OF SCIENTIFIC RESEARCH IN ENGINEERING AND MANAGEMENT
ABSTRACT Sand is one of the constituents used in the production of concrete. Become expensive and also a scarce materials. In view of this there is a need to identify suitable alternative material waste in place of river sand. The utilization of quarry dust which is a waste material has been accepted as building materials in many countries for the ...

Estimation of unconfined compressive strength of stabilized sandy soil with Natural pozzolanic geopolymer using artificial neural networks algorithm

Abstract The main purpose of this research is to analyze the ability of artificial neural network algorithm to estimate the unconfined compressive strength parameter of poor sand stabilized with Natural pozzolanic geopolymer. Due to the importance of sandy soil in engineering projects, this type of soil has been used. The nature of this soil is

Alkaline activation of natural and artificial pozzolans as binders for improving waste soils

Over the years, there has been considerable interest in sustainable construction and the production of alternative materials to those normally used. The reason for this interest lies in the fact that although traditional binders, such as lime and cement, offer excellent mechanical performance and are suitable for various applications, their production ...

Stabilisation of Urmia Lake peat using natural and artificial pozzolans

Proceedings of the Institution of Civil Engineers - Ground Improvement, 2022
Peat generally found in thick layers in limited areas such as Urmia Lake, Iran has low shear strength and high compressive deformation. Therefore, an appropriate soil improvement method is required. This paper presents an experimental study of the stabilisation of Urmia Lake peat on the Urmia–Tabriz highway, 7·8 km to the east of Urmia city in Iran. A
