What Is A Concrete Chipping?

Concrete chipping is a process that involves breaking away dried concrete from the walls of ready-mix concrete trucks and central mixers. This task is typically carried out by trained professionals or by a robotically-controlled machine that uses an ultra-high pressure water source (20,000 psi) to delaminate the concrete from the interior of the mixer drum.

The process starts by cutting the concrete with ultra high pressure water and then human teams use tools such as handheld jackhammers and chisels to manually remove the hardened material.

The discarded concrete is then piled on the ground, where it can be either disposed of in a landfill, recycled into new building materials, or repurposed in some other way.

Why Chipping Is Done On Concrete?

The process of concrete chipping is used in the construction industry to improve adherence on smooth surfaces before plastering. The goal of this project was to design a low-cost concrete chipping machine that is suitable for the construction industry.

A study was conducted to evaluate the available methods and machinery used for chipping concrete, including their suitability and drawbacks. From this research, several designs were proposed and the best one was selected for further development.

Manual calculations were used to determine the dimensions and parameters of the machine. Simulations were also performed to evaluate the wear and tear and stress concentration of the tool, and it was determined that the machine could withstand the forces during impact and achieve sufficient penetration.

The machine was then prototyped. Overall, the attachment used for the grinding machine can be used to chip concrete, but further improvements can be made to enhance the machine’s operation and safety.

Safety During The Concrete Chipping?

Concrete chipping, which is the process of breaking up concrete surfaces, is a dangerous job when done by human teams.

Unlike hydro chipping, which is done by robots and has fewer safety concerns, human chippers face a number of hazards on the job, including flying debris, silica dust, electric shock, and excessive noise. Confined spaces are also a danger that chippers face. Airborne cement dust can cause burns, irritation, blindness, and life-threatening diseases.

To minimize exposure to these dangers, personal protective equipment (PPE) such as hard hats, respirators, eye protection, steel-toe boots, and ear protection is used.

The United States Department of Labor’s Occupational Safety and Health Administration (OSHA) also has a list of safety tips and requirements to protect workers involved in the concrete industry.

Additionally, many companies require continuing education and regular safety training to ensure that their team members and clients are fully protected.

Maintenance Of Concrete Chipping?

The frequency of chipping needed for cement mixing trucks and concrete mixers varies based on factors such as the equipment, concrete blends and maintenance practices.

However, many companies recommend scheduling chipping every 3 months to prevent issues such as reduced drum capacity, slow machinery and breakdowns which can cause costly repairs and interrupt work.

Even companies using chemical blends to prevent buildup still require occasional chipping, though less frequently.
