The Average Lifespan of Concrete

To mix your own concrete for footings and piers, use 1 part Portland cement, 2 parts clean river sand, and 3 parts gravel (maximum of 1 inch diameter and specially washed for concrete mixing).You can also use dry mix or transit mix, which contain the same proportions of cement, sand, and gravel detailed above.The colour… Read More »

How to Mix Your Own Concrete

In its simplest form, concrete is a mixture of paste and aggregates.Cement is actually an ingredient of concrete. It is the fine powder that, when mixed with water, sand, and gravel or crushed stone (fine and coarse aggregate), forms the rock-like mass known as concrete.It is an important construction material used extensively in buildings, bridges,… Read More »

The Average Lifespan of Concrete. Concrete is a durable material that can last a lifetime. The term durability means that something can last for a long period of time without significantly deteriorating. With a durable material such as concrete, the environment is conserved as well as waste reduced.Because concrete slabs “float” on the soil, soft… Read More »

The Average Lifespan of Concrete

Plasticizers are also often used when pozzolanic ash is added to concrete to improve strength.Adding an excessive amount of plasticizer will result in excessive segregation of concrete and is not advisable. Depending on the particular chemical used, use of too much plasticizer may result in a retarding effect.Concrete plasticizers increases the workability of freshly mixed… Read More »


A concrete mixture ratio of 1 part cement, 3 parts sand, and 3 parts aggregate will produce a concrete mix of approximately 3000 psi. Mixing water with the cement, sand, and stone will form a paste that will bind the materials together until the mix hardens.In making concrete strong, these ingredients should usually be mixed… Read More »


The main ingredient of the concrete is cement, aggregates, water and admixtures.The various methods of mix design are applied for determining the qualities & quantity of concrete. The objective of designing a mix is to produce a concrete of required strength, durability and workability as economically as possible.Because concrete slabs “float” on the soil, soft… Read More »

Concrete is the most commonly used man-made material on earth. It is an important construction material used extensively in buildings, bridges, roads and dams. Its uses range from structural applications, to paviours, kerbs, pipes and drains.The key to successfully pouring concrete over an existing concrete surface is to ensure the two layers bond properly. Even… Read More »

Rainwater can cause a new concrete surface to become soft, which in turn decreases the abrasion resistance and strength of the concrete, while increasing the tendency for dusting and cracking to develop. The key to preventing damage to the concrete surface by a rainstorm is proper preparation and timing.Type 2 – Is used for structures… Read More »

Pouring Concrete

But material limitations, design and construction practices, and severe exposure conditions can cause concrete to deteriorate, which may result in aesthetic, functional, or structural problems. Concrete can deteriorate for a variety of reasons, and concrete damage is often the result of a combination of factors.Concrete placement is an important process in the construction that determine… Read More »

Types and Causes of Concrete Deterioration

Poured concrete foundation walls that are less than 8 feet tall and have soil outside that is 6 or 7 feet deep against the wall can often be 8 inches thick and function quite well. As soon as you go higher or have greater depths of soil pushing against the wall, you need to increase… Read More »
