- Mix Design Options: We offer a range of ready-mix concrete designs, from GEN1 for general use in domestic applications, to RC50 for more demanding projects such as motorway precast concrete. Each mix is tailored to meet the specific requirements of the job.
- Admixtures for Enhanced Durability: To further improve the strength and durability of our concrete, we use admixtures that help adapt to varying environmental conditions. These include liquid retarders to slow the curing process in hot weather, air-entraining agents (AEA) to prevent cracking during freeze-thaw cycles, and accelerator admixtures that ensure rapid strength development within 24 hours.
How We Extract Our Stone: The Quarrying Process
At Armstrongs, the extraction process is carefully planned to ensure that each type of stone is sourced efficiently while maintaining its natural quality. The method we use depends on the intended purpose of the stone—whether it’s being processed into aggregates for construction or precision-cut for bespoke architectural features.
Our team of skilled quarry workers and technicians use both advanced technology and traditional techniques to extract and shape stone that meets the highest industry standards.
Blasting: Efficient Extraction for Large-Scale Aggregates
Blasting is one of the most common techniques used for extracting stone in large quantities, particularly when we need to produce aggregates for construction projects. This method involves the controlled use of explosives to break stone away from the rock face.
How Blast Technicians Prepare and Execute Quarry Blasts
Before any blast takes place, our expert blast technicians prepare the rock face by drilling carefully measured holes in the stone.
These holes are filled with explosives, and everything is set up to ensure a controlled detonation. Once the explosives are in place, the technicians will detonate them from a safe distance, causing the stone to break into manageable pieces.
Uses of Blasted Stone
The stone that is dislodged during the blast is mainly used for aggregates, which are an essential material in construction.
The larger pieces of stone may also be broken down further for use in other applications, depending on the specific needs of the project. Aggregates are used in a variety of applications, including road building, concrete production, and other infrastructure projects.
Manual Excavation: Precision Extraction for Dimensional Stone
When we need to extract stone for more delicate uses, such as dimensional stone or bespoke architectural features, we turn to manual excavation. This method is slower and more precise, ensuring that the stone remains in good condition for later shaping and finishing.
The Role of Excavators and Ripper Attachments
In manual excavation, we use excavators equipped with ripper attachments to carefully remove stone from the quarry face. The ripper attachment works by gently pulling the stone from its natural position, making sure the stone’s integrity is maintained.
Breaking Down Oversized Stone with the Drop Ball Technique
Sometimes, the stone we extract is too large to transport in its raw form. In these cases, we use a drop ball technique to break down the oversized stone into more manageable pieces.
A large metal ball is dropped from a height onto the stone, cracking it into smaller, more usable sections. This method is especially useful when dealing with hard, dense stones that require extra force to break down.
What happens next?
Once the stone is extracted there are a number of different processes that we undertake depending on the finished product.
From Quarry to Product: The Stone Processing Journey
Once the stone has been extracted, it’s ready to be processed into the high-quality products our customers rely on. The processing journey is where raw stone is transformed into the various products Armstrongs offers, whether that’s aggregates, cut stone, or bespoke stonework for architectural projects.
Crushing, Screening & Washing: Preparing Aggregates
The first step in preparing the stone for sale is to process it into aggregates. This involves several steps to ensure that the stone is graded, clean, and ready for use.
Screening to Classify Aggregates by Size
Screening is the first stage of the process, where the stone is sorted by size. This ensures that we can separate the different grades of aggregates for various uses. The material is passed through a series of screens with different-sized mesh to classify it according to its size.
Crushing to Produce Different Grades of Aggregates
After screening, larger stones may be crushed into smaller pieces. Crushing allows us to produce aggregates in a variety of sizes, from fine sand to larger gravel, which can be used for different types of construction and landscaping projects.
Washing to Remove Impurities and Meet Quality Standards
After the stone is screened and crushed, it undergoes a washing process. This is a crucial step, as it removes clay, silt, and other impurities that may have been present in the stone.
The washing process ensures that the aggregates meet quality standards and are suitable for use in construction projects, where purity and consistency are vital.
Saw Cutting: Precision Shaping for Bespoke Stonework
For bespoke stonework, such as dimensional stone for buildings or unique architectural features, precision cutting is essential. At Armstrongs, we use a combination of fixed blade and wire saws to cut the stone into the exact dimensions required.
The Role of Fixed Blade and Wire Saws
Our fixed blade and wire saws are equipped to handle a variety of stone types, cutting them to specific shapes and sizes. These saws ensure that each piece of stone is cut with precision, allowing us to meet our customers’ exact requirements.
Shaping Dimensional Stone for Architectural Applications
Once the stone has been cut, it is carefully shaped to suit its intended use. Whether it’s a window sill, lintel, or decorative stone feature, our saws can produce clean, straight cuts that are perfect for architectural applications.
Hand-Finished Cut Stone: Craftsmanship at Its Finest
For the final step in creating bespoke stone products, our skilled stonemasons apply their expertise to refine and detail each piece. Hand-finishing adds the personal touch that makes our stone products unique.
The Role of Stonemasons in Refining and Detailing
Stonemasons play a crucial role in the final stages of stone processing. They use hand tools to refine and polish each piece of stone, adding intricate details such as chamfers, bevels, and textures.
This craftsmanship ensures that every stone product is not only functional but also aesthetically pleasing.
