Construction material testing is critical for the viability and safety of a construction project. Hence, 1. It can reveal any number of issues related to construction quality. 2. It can highlight future risks, help classify a building site, and assist with engineering decisions. 3. Without construction material testing, engineers and builders may not know if the quality of the construction meets the requirements.  Familiarization with apparatus & equipment used in testing of materials Why Is it Important to Be Familiar With Laboratory Apparatus & Their Uses? Before getting indulged with the science instruments or chemicals, it is quite important to have the accurate information regarding it. A. Safe Handling - laboratory equipment can lead to dangerous side effects and that is why it is quite important to know how to handle properly. B. Efficient Use - Laboratory instruments required the proper knowledge to run or operate them. If they are not operated in the required way, it will not be helpful to churn out the desired results.  Familiarization with apparatus & equipment used in testing of materials Why Is it Important to Be Familiar With Laboratory Apparatus & Their Uses? Before getting indulged with the science instruments or chemicals, it is quite important to have the accurate information regarding it. C. Proper Materials - Many laboratory machines are designed to study and analyze samples from a variety of sources. This sample could be organic or inorganic, vegetable or mineral. Knowing which machine is for which kind of sample and what the machine is supposed to do is good for avoiding trouble.  Familiarization with apparatus & equipment used in testing of materials Why Is it Important to Be Familiar With Laboratory Apparatus & Their Uses? Before getting indulged with the science instruments or chemicals, it is quite important to have the accurate information regarding it. D. Understanding Results - After inserting the correct materials or calibrating a machine correctly, you still won't be able to finish your task unless you understand what it is that the machine has just done. Knowing which sections of any printouts or displays contain the most vital information and what that information means is important to completing the experiment.  Familiarization with apparatus & equipment used in testing of materials The Apparatus and Equipment used in testing materials Civil engineering projects largely depend on the quality of their materials; therefore testing equipment capable of providing consumers with accurate and repeatable results is imperative. While the mechanism in which the equipment performs analysis procedures varies depending upon the material to be analyzed, these testing instruments are capable of analyzing the properties of the materials such as aggregates, soil, concrete, and asphalt.  Familiarization with apparatus & equipment used in testing of materials The Apparatus and Equipment used in testing materials A.
