What is Concrete? Concrete is a construction material composed of cement, fine aggregates (sand) and coarse aggregates mixed with water which hardens with time. Portland cement is the mostly used type of cement for production of concrete. There are different types of binding material is used other than cement such as lime for lime concrete and bitumen for asphalt concrete which is used for road construction. Various types of cements are used for concrete works which have different properties and applications. Some of the type of cement are Portland Pozzolana Cement (PPC), rapid hardening cement, Sulphate resistant cement etc.
Components of Concrete Components of concrete are cement, sand, aggregates and water. Mixture of Portland cement and water is called as paste. So, concrete can be called as a mixture of paste, sand and aggregates. Sometimes rocks are used instead of aggregates. The cement paste coats the surface of the fine and coarse aggregates when mixed thoroughly and binds them. Soon after mixing the components, hydration reaction starts which provides strength and a rock solid concrete is obtained.
What is Grade of Concrete? Grade of concrete denotes its strength required for construction. For example, M30 grade signifies that compressive strength required for construction is 30MPa. The first letter in grade “M” is the mix and 30 is the required strength in MPa. Based on various lab tests, grade of concrete is presented in Mix Proportions. For example, for M30 grade, the mix proportion can be 1:1:2, where 1 is the ratio of cement, 1 is the ratio of sand and 2 is the ratio of coarse aggregate based on volume or weight of materials. The strength is measured with concrete cube or cylinders by civil engineers at construction site. Cube or cylinders are made during casting of structural member and after hardening it is cured for 28 days. Then compressive strength test is conducted to find the strength. Regular grades of concrete are M15, M20, M25 etc. For plain cement concrete works, generally M15 is used. For reinforced concrete construction minimum M20 grade of concrete are used
Different Types of Concrete Construction Concrete is generally used in two types of construction, i.e. plain concrete construction and reinforced concrete construction. In PCC, it is poured and casted without use of any reinforcement. This is used when the structural member is subjected only to the compressive forces and not bending.
When a structural member is subjected to bending, reinforcements are required to withstand tension forces structural member as it is very weak in tension compared to compression. Generally, strength of concrete in tension is only 10% of its strength in compression. It is used as a construction material for almost all types of structures such as residential concrete buildings, industrial structures, dams, roads, tunnels, multi storey buildings, skyscrapers, bridges, sidewalks and superhighways etc. Example of famous and large structures made with concrete are Hoover Dam, Panama Canal and Roman Pantheon. It is the largest human made building materials used for construction.
Steps of Concrete Construction The construction steps are: Selecting quantities of materials for selected mix proportion Mixing Checking of workability Transportation Pouring in formwork for casting Vibrating for proper compaction Removal of formwork after suitable time Curing member with suitable methods and required time.

How to Make Concrete? Concrete is manufactured or mixed in proportions w.r.t. cement quantity. There are two types of concrete mixes, i.e. nominal mix and design mix. Nominal mix is used for normal construction works such as small residential buildings. Most popular nominal mix are in the proportion of 1:2:4. Design mixed concrete are those for which mix proportions are finalized based on various lab tests on cylinder or cube for its compressive strength. This process is also called as mix design. These tests are conducted to find suitable mix based on locally available material to obtain strength required as per structural design. A design mixed offers economy on use of ingredients. Once suitable mix proportions are known, then its ingredients are mixed in the ratio as selected. Two methods are used for mixing, i.e. Hand Mixing or Machine Mixing. Based on quantity and quality required, the suitable method of mixing is selected. In the hand mixing, each ingredients are placed on a flat surface and water is added and mixed with hand tools. In machine mixing, different types of machines are used. In this case, the ingredients are added in required quantity to mix and produce fresh concrete. Once the it is mixed adequately it is transported to casting location and poured in formworks. Various types of formworks are available which as selected based on usage. Poured concrete is allowed to set in formworks for specified time based on type of structural member to gain sufficient strength. After removal of formwork, curing is done by various methods to make up the moisture loss due to evaporation. Hydration reaction requires moisture which is responsible for setting and strength gain. So, curing is generally continued for minimum 7 days after removal of formwork.
How to Hire a Concrete Contractor? When hiring a concrete contractor, you may want to hire the most reliable contractor you can find. It saves both of your time, money and effort. In order to hire a reliable contractor, here are 5 basic tips on how to hire one.
Post Your Ad You can either post your ad that you are looking for a concrete contractor online or on your local newspaper or ad directories.

Contact The Contractors Once you have posted your job offering, set a specific number of days until when you will be accepting applicants. Once you have enough applicants or the deadline has been reached, you can now go through each application while noting some promising contractors. You can now then contact them either phone call or email and schedule an interview or a visit. Get Estimates During the interview or when you visit the office of the contractor, don't forget to ask for an estimate. Most concrete contractors now provide free estimate just to let their client knows how much would the entire project roughly cost. If the contractor is asking even for a small fee before giving you some estimates, it would be best to walk away from them. Estimates should be given to the client without any fees being asked. Written Contract is a Must Once you are satisfied with the estimate given by the contractors you want to hire, ask them to make a written contract. The contract should contain all necessary information such as the work involve, the payment, payment method, consequences once the project would not be completed and a lot more. Make sure to read all of the things written in the contract before signing it. Pay Upon Completion After the project has been completed, it is now your turn as the client to do your part. You need to check the work done by the concrete contractor and pay accordingly. You do not need to pay until the job has been completed or until you are satisfied with the work that has been done. Some contractors would have no problem fixing the job because it is included in their warranty service.
How to Find the â€‹Best Concrete Contractorâ€‹?Â
Hiring a concrete contractor instead of laying concrete yourself is always a good decision because working with concrete requires some experience and special equipment. There are few general tips we can provide you with so you can avoid problems and hire a reliable contractor. You can start you search for a contractor by asking you co-workers, friend or neighbors for recommendations. Check out the concrete work that was done for them, how it looks today, how long ago it was done and in what shape the concrete is right now. If someone you know is happy with their concrete project, contact same contractor to arrange a meeting. Another good place to find a contractor is local concrete supplier stores. They definitely know all local concrete contractors and can give you recommendations. Some stores have their own concrete contractors' team and you can get an appraisal at no cost. Before you hire a contractor make sure to ask them few questions to see how experienced contractor is and if he has all necessary licenses and ability to get permits. Here is a list of question you need to ask your potential contractor: • How long have they been laying concrete and installing pavers? • Can they provide you with references from previous jobs? • Can you contact their references and inspect the jobs? • Check their liability insurance certificate and proof of Worker Compensation Insurance • Will they provide a written, itemized proposal that includes starting and completion dates, demolition and excavation paving and base materials, taxes and terms of payment? • Do they guarantee their work for one year? Will they return in a year to inspect it? Good concrete contractor should be able to answer all these questions. Before signing the contract, read through it one more time to make sure all aspects of the concrete project are covered and your concrete contractor can start on it.
