Glycolic Acid: Nature's Answer To Hardened Cement

Glycolic Acid-based concrete remover formulations are increasingly sought after by construction professionals aiming to maintain their tools, equipment, and vehicles in top condition. This naturally occurring acid offers a superior solution for prolonging the lifespan and enhancing the performance of construction machinery. By effectively reducing the buildup of hardened cement residues, glycolic acid prevents mechanical wear and tear, which can lead to costly repairs or replacements. 

Furthermore, its eco-friendly nature ensures that while cleaning tasks are efficiently managed, the environmental impact remains minimal. The adoption of glycolic acid not only supports the rigorous demands of construction site maintenance but also upholds high operational standards essential for industry success.

Benefits of Glycolic Acid

 
Glycolic acid boasts several remarkable attributes that make it an exceptional choice for construction professionals seeking to manage hardened cement. Firstly, its efficiency and rapid action ensure that the acid quickly penetrates and loosens concrete, providing speedy results when time is of the essence. 

Another significant advantage of glycolic acid is its low to negligible corrosivity on most metals, which is crucial for preserving the integrity of construction tools and equipment. This quality minimizes potential damage and prolongs the lifespan of valuable assets. 

Glycolic acid is also readily biodegradable, making it an environmentally friendly option compared to many other chemical removers. Its natural occurrence in the environment further enhances its appeal, aligning with the growing demand for sustainable and eco-conscious solutions. Therefore, glycolic acid emerges not just as a powerful agent for removing cement, but also as a safe and responsible choice in the construction industry, balancing high performance with environmental stewardship.

Glycolic Acid Complexing Ability

 
Glycolic acid is one of the most effective acids at complexing calcium ions, offering distinct advantages over common mineral acids like hydrochloric and phosphoric. Its ability to form strong, stable complexes with calcium ions plays a crucial role in breaking down the cement matrix, leading to efficient removal without the aggressive corrosion often associated with stronger mineral acids.

Glycolic acid’s gentler nature also ensures that it can be used on a variety of surfaces without compromising their integrity, making it an ideal choice for construction professionals concerned with maintaining the longevity of their equipment. The reduced corrosivity of glycolic acid not only extends the lifespan of tools and machinery but also reduces maintenance costs and downtime, which are essential factors in high-paced construction environments. 

Lastly, glycolic acid's capability to perform effectively at lower concentrations than some of its counterparts further solidifies its position as a versatile and economical option for those in the construction industry.

The below table illustrates the corrosivity of glycolic acid vs the common mineral acids, phosphoric and hydrochloric.

Glycolic Acid Formulations

 
PureTech Scientific Glycolic Acid, previously manufacured by Chemours, can be easily formulated into ready to use or concentrated cleaning products. See below for starting point formulations. 

Instructions

 

Concentrate

1. Dilute 1:4 with tap water for use.
2. Spray onto surface needing concrete removal.
3. Wait at least 30 min (allowing to react overnight or between shifts is acceptable).
4. Powerwash equipment and parts to remove residual concrete.

• Extremely heavy residuals may require two treatments.
• Wear appropriate personal protection equipment.
• As with all acids, it should not be sprayed on hot surfaces.
