Bricklaying in Dursley

Cement is a crucial element in bricklaying that’s widely used in both construction as well as finishing works. Generally, they’re used to aerate concrete blocks, connect bricks, prepare plaster, floor levelling as well as the making of precast products. The major reason cement is one of the most common construction materials as its incredible ability to hold structure together. To get a cement plaster, you’d simply have to mix cement with both water and sand. However, when you mix cement with lime, sand and water, you’ll get a mortar.

For cements mortars to be used inside joints, you’ll have to include 1 part cement at the minimum to not more than 2 parts sand by weight which should be dry mixed and moistened with enough water to allow for troweling and packing without falling apart. Generally, the cement sand ratio in a mortar is in between 1:2 to 1:6. The cement and sand mix ratio is largely based on the importance of the project.

Cement provides a plethora of uses in bricklaying and these includes:

• Preparation of cement concrete

• Preparation of cement mortar

• Building fireproof and thermal proof structures

• Building chemical proof structures

• Serving as a grout material

• Building hydrographic and frost resistant structures

• Manufacturing precast members

• Constructing aesthetic concrete

• Constructing cement concrete roads

There are several types of cements with each having its specific purpose. For instance, the type of cement more suited to building a fire proof structure is a high alumnia cement and to build a hydrographic structure, cements like expanding cement, hydrophobic cement, pozzolana cement and quick setting cement are the best bet. Acid resistant cements are more useful in building chemical proof structures, portland cements are best suited to making grout materials, while coloured cements are preferable to building aesthetic structures.

When it comes to laying of bricks, it is essential to get the right mortar mix. It is vital, be it for construction or maintenance projects, so far mortar is required. There are several materials incorporated in getting mortar which includes both cement and sharp sand, soft sand or plasterer’s sand and lots more. Here, we are going to look at the right ratio for cement and sand mix in bricklaying.

Cement include ingredients such as iron, aluminium, as well as silicon and it is mainly used for mortars like aerated cement mortar, Portland cement mortar and gauged mortar. Sand, on the other hand, comes in different forms such as sharp sand, soft sand and plasterer’s sand. The sharp sand consists of a larger grain size than the others and is usually incorporated in the construction areas that requires more strength as well as flexibility. Soft sand is the most common one used in mortar and it’s also referred to as bricklayers’ sand. These are used to make all types of mortar. Finally the plasterer’s sand which neither has the sharp sand’s coarseness nor the fineness of the soft sand, but can also be used for any form of mortar.

Cement and sand mortar is used for a plethora of bricklaying jobs serving as a glue for bricks, walls and pillars, while also repairing or maintaining old listed buildings. The preferred ratio here is 1:3 to 1:5 of cement and building sand. Meanwhile, to get a sand cement mix, essential materials that are required includes water, soft building sand as well as cement. However, you must also note that a sand and cement mortar is not used for structural projects, rather a concrete ratio is used.

Yes, bricklayers can work during the cold months, but it all depends on the type of work involved. For instance, residential housing maintenance works such as tuck pointing deficient mortar joints on exterior walls and columns as well as rebuilding of chimneys are best tackled during summer or simply put, the warmer months of the year. This is is mainly because the best results for these activities are achieved in the warmer months and several bricklayers will agree to this fact.

Mixing of mortar using anti-freeze technique to counter-act the effects of a cold weather can lead to white marks trailing down the brick when warmer temperatures comes knocking. As a result, even mortar mixing should be done at temperatures exceeding zero degree farenheit which will hold no serious consequences if the temperature should change to a little bit below the norms. During the winter, a good technique that can be incorporated to when mixing mortar would be to mix them in smaller quantities in a warmer environment. These small quantities will immediately be fed by the labourers to the bricklayers and in such circumstances, the mixed mortars will not be subjected to a freezing temperature for too long.

Generally, it would be very unwise to consider any bricklaying work to be done whenever the temperature jumps to a certain level which would be considered to be very inconvenient to work in. Interior works like remodelling of fireplaces can be tackled so long there is a warm space to mix the mortars while also keeping the materials at an indoor temperature. Bricklaying works that have, however, been completed during the colder months should be subjected to a very close inspection as well as looking for potential damage that can be caused to existing works as a result of the harsh weather.

Well, just like many other team work, a bricklayer is only as good as his supporting cast. And a hard-working labourer should be able to keep three bricklayer gangs happy. But even when he gets to serve just one bricklayer, the site conditions and nature of the wall can also play a huge role in determining the number of bricks that can be laid within 24 hours.

With the best possible site condition, hard-working labourer and best scenario with no pillars, no face brick, long straight wall and no wall ties, a well trained bricklayer should be able to lay within a range of 800 to 1100 bricks all day long. However, you rarely get walls like this as there is always going to be some corner or curve somewhere which usually takes some time to get right. Furthermore, once the bricklayer has laid up to 5 feet, there’ll be a need to get some lift. From that point onwards, the job understandably gets slower and tougher - meaning there’ll most definitely be a face brick.

In addition, there are multiple other factors that can affect the number of bricks that can be laid in a day. Sometimes its the complex designs or weather that’ll determine the daily rate.

With the aforementioned factors and more realistically, on a good day and great site, an expert bricklayer should be able to lay about 500 to 800 bricks in a day. This is generally a very good target, but of course you never can tell with the reasons above and other factors that are simply beyond the control of the bricklayer. If you have a project and want it completed as soon as possible, you can pay the bricklayers based on the number of bricks laid to increase their efficiency.
