Expansion agent for concrete "Pacific Expand"

Expansion agent for concrete "Pacific Expand"

The excellence has been demonstrated in a wide range of fields, including the manufacturing of high-strength concrete products!

"Pacific Expand" is an expansive agent that significantly reduces drying shrinkage and cracking in concrete. Due to its high hydration bonding capacity, it achieves a good expansion effect without compromising concrete strength. We offer a lineup including structural types suitable for reducing concrete cracking, as well as early-strength expansive agents. 【Features】 ■ The expansive force works effectively, providing stable results ■ Minimal loss of expansive force during the initial hydration stage ■ Effective expansion can be achieved with a small amount of usage *For more details, please refer to the PDF document or feel free to contact us.

Expanding agent for concrete products - Pacific Gypsum

Expanding agent for concrete products - Pacific Gypsum

Improve the durability of precast concrete and aim for the longevity of precast products!

"Pacific Jipukar" is an expansion agent for concrete products primarily composed of lime. When mixed with this product, precast concrete subjected to steam curing can reduce cracking due to drying shrinkage and introduce chemical prestressing. Additionally, the properties of fresh concrete are similar to those of regular concrete, and by using it in conjunction with an early strength accelerator, the development of early strength can be enhanced. [Features] ■ Capable of suppressing cracks caused by drying shrinkage and introducing chemical prestressing ■ The properties of fresh concrete are similar to those of regular concrete ■ Enhances the development of early strength when used in combination with an early strength accelerator *For more details, please refer to the PDF materials or feel free to contact us.

Expansion agent for low-addition concrete Pacific Hyper Expand

Expansion agent for low-addition concrete Pacific Hyper Expand

Crack Prevention: It suppresses cracks in concrete and improves durability!

"Pacific Hyper Expand" is a low-additive expansion agent for concrete that significantly reduces concrete cracking. Concrete using this product expands during the early curing stage (age 1-7 days) compared to ordinary concrete, with an expansion rate of 150-250×10^-6, thereby reducing long-term shrinkage and suppressing cracking. We offer a lineup of structural types effective in suppressing cracking due to volume changes in general concrete structures, including those designed to mitigate hydration heat. 【Features】 ■ Compliant with JIS A 6202 "Expansion Agents for Concrete" (structural type) ■ Significantly reduces concrete cracking ■ Effective expansion achieved with a small amount of use ■ Slump and air content changes over time are comparable to ordinary concrete ■ Applicable to a wide variety of concrete types *For more details, please refer to the PDF document or feel free to contact us.

[Information] Measures Against Concrete Cracking - 4 Selections -

[Information] Measures Against Concrete Cracking - 4 Selections -

We will introduce proposals for suppressing cracks caused by drying shrinkage and thermal stress!

Cracks in concrete can occur due to drying shrinkage, temperature stress, or when volume shrinkage is restrained for some reason due to sudden changes in temperature or humidity. Additionally, after construction, cracks can develop due to rebar corrosion caused by concrete carbonation or salt damage, as well as structural cracks resulting from earthquakes or ground subsidence. These cracks not only detract from aesthetics but also lead to functional deterioration, water leakage, and ultimately, partial collapse of the structure. The crack prevention measures introduced in this document are proposals aimed at suppressing cracks caused by drying shrinkage and temperature stress, to be applied during the construction of concrete structures. [Contents] ■ Initial crack prevention measures ■ Drying shrinkage crack prevention measures ■ Temperature crack prevention measures ■ Self-shrinkage crack prevention measures *For more details, please refer to the PDF document or feel free to contact us.
