How to Make Concrete More Durable

Concrete Colorado Springs are the most commonly used construction material in the world. It’s found in roads, sidewalks, houses, buildings, dams, canals, and even missile silos.


It is a hard, strong, and conglomerate construction material made by mixing cement with aggregates such as sand, pebbles, crushed rock, or slag. It can be shaped to produce any kind of structure.

Concrete is one of the most popular construction materials in use today. It is used to build roads, sidewalks, buildings, and bridges, and it is even found in a few of the world’s tallest skyscrapers. Concrete is a material that consists of cement mixed with sand and different types of aggregates. It is then poured into temporary vessels and allowed to harden through hydration. The strength of concrete can vary widely, depending on the mix design and curing conditions.

The compressive strength of concrete is measured in psi, or kilograms per square centimeter. It has much lower tensile strength, however, so it is generally reinforced with materials that are strong in tension (often steel). Concrete also has a low coefficient of thermal expansion and shrinks as it matures. These properties are important in determining the final characteristics of a concrete structure and can be used to predict how it will behave under varying conditions.

Because it is so durable, strong, and versatile, concrete is found in many different forms and applications around the world. It is most commonly used in building structures such as foundations, floors, and walls. Concrete is also very suitable for the manufacture of precast elements, such as beams and slabs, because it can be shaped into various shapes and sizes with minimal effort using molds.

In addition, concrete is very cost-effective and easy to work with. It can be molded into just about any shape, and it can be made to be extremely durable by adding reinforcement or admixtures. Concrete is a non-combustible material and provides good resistance to fire.

High-strength concrete is usually made with a special mixture of cement, sand, and coarse aggregates that have been designed and mixed to specific ratios with water. It is often modified with chemical admixtures, such as superplasticizers and retarders, which can give it adequate workability at relatively low water-cement ratios. Air-entraining admixtures can also be used to enhance its flowability.

Recycled industrial waste products can also be added to a concrete mix, such as fly ash, silica fume, ground granulated blast furnace slag, and waste glass. These substitutes for conventional cement can increase its strength while decreasing the environmental impact of concrete production. In addition, they can improve some of its properties, such as its durability and reactivity to alkalis.


The durability of concrete is its ability to withstand damage or deterioration without significant loss of strength. This resistance allows structures to be built where they might otherwise not be possible. Concrete can withstand large deformations and loads, including earthquakes and blasts. It also has good resistance to corrosion and can withstand natural weathering. However, if it is exposed to too much moisture, it can deteriorate quickly. Concrete can be designed to be durable, and there are a number of ways it can be made more so.

The amount of water in a concrete mix has a direct impact on its strength and durability. Concrete with a lower water content is stronger and more resistant to deterioration than concrete with a higher water content. It is therefore important to get the right mixture of water and cement.

In addition to the water content, other factors can have an impact on the durability of concrete. One of these is the alkali-aggregate reaction, which can cause severe cracking and spalling in concrete. Using cement with less alkali, non-reactive aggregates, and pozzolanic materials can help reduce this effect.

Another factor is the ability of concrete to resist changes in temperature. Concrete can be made more resilient by keeping it damp after pouring to slow down the process of drying out. This can be achieved by spraying it with water or by adding chemical admixtures to the mix.

Finally, the ability of concrete to relieve internal stresses is crucial to its durability. This is known as creep. Concrete with a high creep capacity can be subjected to large deformations before it cracks. This is important for bridges and other long-span structures. The way in which concrete creeps is affected by the water content, the aggregate size and type, and the placement method.

It is not always easy to design concrete with a high level of durability, but it is possible. By using the correct mix, placement, curing methods, and service environment, concrete can be made more durable. This can help reduce the need for repairs and replacements, which saves money as well as reducing waste and environmental impacts.


Concrete is a highly durable and remarkably versatile material that can be recycled. It is made from a mixture of aggregates (crushed stone, gravel, and sand) and a binding agent (cement). Typically, Portland cement is used as the binding agent; however, there are many other types of cement that can be used, including fly ash, blast furnace slag, and bottom ash from thermal power plants. Using these materials reduces the amount of energy required to produce cement as well as the carbon footprint of the concrete produced.

When a structure or roadway is demolished, there is often a large amount of unusable concrete left behind. This concrete can be recycled to provide aggregate for new structures and roadways or as a base material underneath asphalt, concrete, paving stones, and stone driveways. Recycled concrete is also a cost-effective alternative to other forms of aggregate, such as crushed stone or gravel. It is estimated that recycling one ton of concrete saves around 1,700 kg of CO2 and 5,746 liters of water.

The concrete industry is working hard to make the production of concrete a more sustainable process by reducing its environmental impact, improving its properties, and utilizing recycled aggregates. There are a number of different ways to achieve this, from using more sustainable concrete mixtures that minimize the use of raw materials to utilizing recycled concrete for applications where durability is not critical, such as roads and runways.

There is even research on making concrete completely recyclable, a concept known as “Completely Recyclable Concrete” (CRC). The goal of CRC is to design a mix that can be completely recycled within the cement production process. This would drastically reduce the demand for primary raw materials and greatly lower the environmental impact of concrete production.

The most obvious application for concrete is the construction of buildings and other infrastructure. Its strength, longevity, and insulating properties make it an ideal choice for many applications. In addition, concrete can be recycled and reused after it is no longer needed, ensuring that the material does not end up in landfills.


As a construction material, it is cost-effective, readily available, and easily adapted to suit different applications. It is also relatively environmentally benign compared to most alternatives and can be recycled indefinitely, transforming into aggregates or other useful materials. Concrete has a low permeability, making it durable and watertight. It has excellent abrasion resistance and can be poured into formwork to create curved surfaces.

Its most common application is in building and infrastructure. This ranges from floors to roads and bridges. Its strength and durability make it ideal for use in foundations and for bearing loads, including heavy vehicles and cranes. Its ability to resist corrosion from re-inforcing steel and chloride-rich road salts means that it can endure a long lifespan, especially when protected with coatings.

Despite these attributes, concrete is not without its environmental costs. It is one of the three primary producers of carbon dioxide, a major greenhouse gas, and most of these emissions are from its production. The combustion of raw materials to produce clinker and the calcination process release carbon dioxide into the atmosphere.

The use of fly ash and GGBFS (ground granulated blast furnace slag) in the mix reduces this impact. Many industrial waste products can be used as a substitute for cement or aggregate, such as ground vehicle tires and glass, reducing the need to extract natural resources.

Once mixed, concrete can be readily placed wherever it is required, usually within a few hours of manufacture. It can be poured free-flowing, pumped through pipes, or dropped in a trench or tremie, and it can even be transported by truck to where it is needed.
