introduction of concrete as a construction medium and the true arch as a structural component made it possible for the Romans to build strong‚ elaborate‚ expansive structures that would endure the test of time. Concrete Roman concrete‚ called opus caementicium‚ was made by mixing traditional lime mortar with stone aggregate called caementa. This material used less water and was very thick compared to modern concrete; therefore it was laid rather than poured (Roman Architecture‚ n.d.). Concrete was an important

Aggregates is a major part of concrete‚ it is of urgent need that we look into the influence of aggregate on the fresh as well as hardened properties of concrete. Better grading of aggregate not only will show better results in the properties of the concrete but will also help in saving expensive materials such as cement‚ fly ash and admixture. In the comparative study of influence of the aggregate on high strength concrete‚ here is an attempt to study strength characteristics of cubes and cylinders

CONSTRUCTION METHODS AND TECHNOLOGY READY MIX CONCRETE SUBMITTED TO: SUBMITTED BY: PROF. SACHIN JAIN SONABH DHARIWAL VARUN GOEL [pic] INTRODUCTION: Ready-mix concrete is a type of concrete that is manufactured in a factory or batching plant‚ according to a set recipe‚ and then delivered to a worksite‚ by truck mounted transit mixers. This results in a precise mixture‚ allowing specialty concrete mixtures to be developed and implemented on construction

Advantages of mix design Mix design aims to achieve good quality concrete at site economically. I. Quality concrete means • Better strength • Better imperviousness and durability • Dense and homogeneous concrete II. Economy a) Economy in cement consumption It is possible to save up to 15% of cement for M20 grade of concrete with the help of concrete mix design. In fact higher the grade of concrete more are the savings. Lower cement content also results in lower heat of hydration and hence

These include novel concepts regarding the legal system‚ Roman numerals‚ architecture and the Roman calendar. However‚ the development of concrete as a building material is not the first thing that comes to mind when considering the Roman contributions to civilization. While the use of concrete predates the Roman era‚ the Romans discovered important

ABSTRACT Concrete has been the most preferred construction material for over five decades. It is being increasing day to day all over the world due to its versatility‚ mould ability‚ high compressive strength and many more advantages. For several years beginning in 1983‚ the problem of the durability of the concrete structures was a major topic of interest in Japan. The creation of durable concrete structures requires adequate compaction by skilled workers. One solution for the achievement of durable
