Engineering B45 Concrete Lab Report Introduction: Concrete is a mixture of sand and rock or similar inert material (aggregates) held together by a cementing material. Usually the cementing material is Portland cement‚ but sometimes binders such as asphalt or gypsum are used‚ in which case the concrete may be called asphaltic concrete or gypsum concrete. Properties of concrete are governed not only by the properties of its ingredients (cement‚ water‚ sand‚ and coarse aggregate) but also‚ to a great

Objective The purpose of this lab is to determine the particle size distribution of the fine and coarse aggregates by sieving. Equipment and Material Balance‚ sensitive to within 0.1% of the weight of the sample to be tested Standard sieves for grading of fine aggregates- 4.75 mm‚ 2.36 mm‚ 1.18 mm‚ 300m‚ 150m (# 4‚ 8‚ 16‚ 50 and 100) Standard sieves for grading coarse aggregates- 1 ½ in.‚ 1 in.‚ ¾ in.‚ ½ ‚ 3/8 in.‚ 4 in‚ plus a 4.75 mm(#4 sieve) Fine (0.5 Kg) and coarse (2 to 20 Kg depending

The size of its particles is smaller than 0.85mm (Pass through 15 B.S. sieve) and bigger than 0.60mm (Retain at 25 B.S. sieve).

Applied Engineering science report. Michael Connor B00240227 Part A: Several mixtures of cement‚ aggregate‚ sand and water were mixed at different ratios to workability and compressive strength. The dry materials of the mixture were mixed and water was gradually added‚ the mixture was then placed in a cube and allowed to dry forming the concrete testing cube. Each of the four blocks containing different compositions of each material were then placed in a compressive testing machine and when

required to produce a concrete mixture based on the BRE Manual Design of concrete mixtures which is attached to this report. It is then used to produce concrete cubes and prisms. The objective of this experiment is to learn the methods of producing concrete and concrete characteristics as well as comparing the theoretical values of the concrete’s Young’s Modulus with experimental values. Procedure for concrete mix: A concrete mix was designed based on the BRE Manual Design of concrete mixtures. Then

Introduction Concrete mixtures can be designed to provide a wide range of mechanical and durability properties to meet the design requirements of a structure. The compressive strength of concrete is the most common performances measure used by engineer in designing buildings and other structures. The compressive strength is measured by breaking concrete specimen in a compression-testing machine. The compressive strength is calculated from the failure load divided by the cross-sectional area resisting

of Concrete and their Sustainability Concrete was first made with fragments of stone or sand mixed with cementatous materials and water. Concrete has changed over the many years and today it is made with basically the same materials‚ but the main differences between concrete when it was first made and now‚ is the concretes strength and that it is produced in larger amounts. Some of the different types are: • Reinforced concrete • Prestressed concrete • Pre-cast concrete • Concrete Masonry

CHM1032L pre/post lab instructions Preparation is a key to success in this lab. For this reason‚ you are required to thoroughly read through the experiment information presented in the lab manual‚ and complete a pre-lab for each experiment you do. The prelab must be completed prior to the day of the experiment. Each Friday I will ask to see your completed prelab before I allow you to enter the lab. If you have not finished the pre-lab‚ I will not allow you to enter the lab and you will receive

Lab report is one way we used during of after an experiment in a laboratory to subtly record and discuss the experiment. During a lab‚ we sometimes can observe only the physical part of the experiment‚ or may be some visible chemical changes. These changes indicate that the experiment we do is successful or not. However‚ in order to understand and achieve more from just simply doing the experiment‚ we write lab report to more profoundly understand the internal meanings of the experiment we do‚ and
