mining sand and sea sand as fine aggregate in concrete

Use of sea sand as fine aggregate in concrete making

Use of sea sand as fine aggregate in concrete making Concrete is a mixture of cement, coarse aggregates, fine aggregates or sand and water On one hand, the brittle environmental balance of the State is threatened by illegal sand mining from rivers, at the same time, restrictions on sand mining has resulted in inadequate availability of good quality sand

EXPERIMENTAL STUDY ON CONCRETE USING SEA SAND AS FINE

Keywords: Concrete, Sea sand and Fine aggregate. 1. INTRODUCTION . Sand is a unique raw material for the construction industry at present, but contractors say that they have to spend more allocations for obtaining bulk loads of sand for their construction work. Quarry dust is one of alternative raw material for the construction industry, but most contractors and the house owners are not

(PDF) SEA SAND AS FINE AGGREGATE FOR CONCRETE

Sea sand was used as complete and partial the control concrete. No influence of salt content on the replacement of fine aggregates (regular sand). Sea sand with behaviour of the mixtures with respect to workability was specific gravity 2.51 and fineness modulus 2.39 was used. observed. The Sea sand showed lower fineness modulus and bulk Dr

Experimental Study on Suitability of Sea Sand as Fine

River sand has been the most popular choice for the fine aggregate component of concrete in the past, but overuse of the material has led to environmental concerns, the depleting of securable river sand deposits and a concomitant price increase in the material. Therefore, it is desirable to obtain cheap, environmentally friendly substitutes for river sand that is preferably sea sand. The Land

Offshore Sand as a Fine Aggregate for Concrete Production

Keywords: Offshore sand; concrete; fine aggregate; chloride content. 1. INTRODUCTION 1.1 General Due to the recent growth in the construction industry, the demand for fine aggregate is escalating rapidly. River sand has been the most widely used fine aggregate in Sri Lanka and over-exploitation of river sand to meet the demand has led to various harmful consequences such as increase in the

EXPERIMENTAL STUDY ON EFFECT OF SILICA SAND AS PARTIAL

Conventional concrete which is produced by the mixture of cement, coarse aggregates, fine aggregates, and water is less environmental friendly due to calcination and mining of sand in river and sea. Polymer concrete is thus promoted where the cement and fine aggregates are replaced partially within itself. In this study, mechanical properties such
