Drilling through concrete – what to watch for

Products to Watch For When Drilling Through Concrete

When drilling holes in concrete, there is no substitute for quality devices and a sharp masonry drill bit that is also of high quality. If you have an inferior drill with little power, and a dull bit, your holes will certainly not be deep enough, and they will certainly be off-line.

If you utilize quality brand name drills such as DeWalt, Bosch, Black & Decker, or Makita, you will be on the right track. There is no substitute for quality and steady power when you are drilling concrete.

You need to always read the user’s manual of your drill extensively, and get to know your device. Understand and research where all the knobs and controls are located and exactly what they do. You need to know how to set your machine up and it needs to end up being force of habit. You have to be comfortable with how the drill deals with you hanging on to it.

Be sure and set the depth of your hole-to-be. While a few of the machines do have a depth control bar, if it does not discover how to set the depth with a pencil mark, or with masking tape.

Discover how to hold the drill properly while it is running. You will need to hold it like a weapon, with your forefinger in place on the trigger. Be sure to use it as intended if the drill has a manage for your other hand. If the drill does not have an additional handle, place your hand on the back of the housing on the drill while in operation.

Prior to you start to drill, make your mark on the wall with a soft pencil at the point where you are to make the hole. Mark the area with a dot or a little cross, but do not make the mark too large.

Position the suggestion of the bit on the mark and use adequate pressure to hold it in place, however do not press down too tough. You will get make use of to the quantity required by practice. Start out sluggish, and make a shallow hole that will assist the drill.

Now begin to drill in earnest, using a high speed. , if your drill has a hammer function utilize it periodically.. If you don’t have a hammer function, stop every ten seconds and pull back, and begin once more, letting the bit cool. Keep on the exact same tack till you reach the desired depth.

If the drill has a handle for your other hand, be sure to use it as meant. If the drill does not have an additional handle, position your hand on the back of the housing on the drill while in operation.

Now begin to drill in earnest, using a high speed. If your drill has a hammer function uses it occasionally.

Concrete Strength and Density Testing Is Very Important to Determine the Safety of Reinforced Concrete Structures

 

Concrete is such a versatile material that it is very extensively used to build many structures, whether they are for residences, commercial properties, factories, bridges, dams, roads or any structure that requires a durable and strong material. This makes the strength of the concrete being used very vital to ensure the safety of structures.

strength and density concreteThe mix of the concrete is decided by earlier testing of the various ingredients that will be used to make the concrete. These mixes are then made in the laboratory where the desired strength and density of the concrete is then tested. It is then a responsibility of the construction engineers to ensure that the concrete that is manufactured and poured reaches the required strength and density as required by the laboratory and designers.

Normal construction procedures require that samples of the concrete being used is poured into molds to form blocks that can be used to test the strength of the concrete that has been poured into the structure. Building codes are in place which decides the quantum of testing. Concrete density testing gathers strength over time and standards have been set that requires certain strengths to be developed by the concrete over periods of 3, 7 and 28 days. The blocks that have been taken as samples of the concrete have to be kept in the same conditions as the original structure.

The weight of each block is then taken to arrive at the density of the concrete. A number of blocks are taken for each batch of concrete, while tabs are also kept on where this particular batch has been used in the structure. These strengths of all the tested blocks and their densities are noted.

 

 

At times, when the tests show results below what is required, engineers may prefer to go in for other non destructive tests to establish the strength and density of the concrete. There are various methods like rebound hammers, and ultrasonic testing that are in wide use. In very rare cases, quality control engineers may insist on actual load testing of the structure by using dead weight or hydraulic forces and checking that the deflection caused is within accepted standards.
