The "SDP Form," a high-durability embedded formwork that does not require a mold, contributes to the realization of a safe and secure society by streamlining on-site construction and enhancing the durability of structures.
This is a high-durability embedded formwork made of high-strength mortar with a water-cement ratio of 30% or less, reinforced with corrosion-resistant stainless steel rebar to achieve thin and lightweight construction. Instead of conventional embedded inserts, it features the use of truss steel materials for connecting and assembling with internal supports. It is applicable to both new construction and repair/reinforcement of existing structures, meeting the expectations of i-Construction through process shortening and labor-saving. 【Features】 (1) It improves the durability of reinforced concrete structures, particularly effective in high-corrosive environments such as coastal splash zones and roads where deicing agents are applied. (2) The use of truss steel materials ensures that the SDP form and the post-poured concrete are securely integrated, preventing delamination at the interface. (3) It allows for a reduction in cross-section thickness, thereby minimizing the increase in thickness during repair and reinforcement work. It can accommodate restrictions such as architectural limits and riverbed obstruction rates.

basic information
【Structural Performance】 ■ A four-point bending test of the panel was conducted, confirming that SDP foam exhibits behavior as a reinforced concrete member. ■ It is possible to secure a bending strength of over 15 N/mm² even with a reinforcement ratio of approximately 0.6%. ■ The design strength can be controlled by increasing or decreasing the amount of reinforcing steel. *For more details, please refer to the technical materials on our company website.
