NIGP 15016: Curing Mixtures, All Types (for Curing Concrete)

NIGP 15016 Curing Mixtures, All Types (For Curing Concrete), an Item code, encompasses concrete curing compounds, sealers, and related chemical products that state and local governments apply to concrete surfaces during and after placement to control moisture loss and optimize strength development. Recent state and local solicitations show demand for curing mixtures primarily within larger concrete construction and repair projects—including fire station infrastructure improvements, park and recreation facility upgrades, water treatment facility rehabilitation, bridge replacement initiatives, and utility infrastructure work. Issuing bodies soliciting under this code include city public works departments, county commissioners' offices, special districts (municipal water authorities, utility authorities), fire departments, school districts, and community development authorities. Most recent activity centers on as-needed concrete supply contracts where curing compounds and admixtures are part of a bundled ready-mix or concrete repair offering rather than stand-alone curing-product procurements. The City of Santa Cruz Fire Department, City of Olathe, and Pasco County Board of County Commissioners each issued multiple concrete-related solicitations during the past four months, though none explicitly isolated curing mixtures as a discrete line item; curing specifications and admixture requirements are embedded within broader ready-mix concrete, concrete pad installation, and miscellaneous concrete services RFPs and IFBs.

Geographic activity clusters in the Southeast (Florida, Georgia, Mississippi), the Mountain West (Arizona, Colorado), the Midwest (Kansas, Michigan, Wisconsin, Kentucky), and the West Coast (California). The City of Santa Cruz issued an IFB for concrete pad installation at Fire Station #3 (IFB B25-0290, due July 29, 2026) specifying concrete conforming to 2022 California Building Code standards, which typically mandates curing-compound specifications; the City of Olathe posted an IFB for ready-mix concrete furnishing and delivery (IFB-26-0083, due August 21, 2026) covering five concrete types with estimated volumes totaling approximately 4,720 cubic yards, where curing-mixture compliance is inherent to concrete quality specifications; Pasco County solicited miscellaneous concrete and asphalt services on an as-needed basis (IFBSV26102, due August 18, 2026) and concrete fiber and regular ready-mix concrete delivery (IFBBW26096, due June 30, 2026) with place of performance throughout the county. The Kissimmee Utility Authority issued two precast concrete pad, sleeve, and post procurements (AR 26-033-JG cancelled July 1, 2026; AR 26-050-JG rebid, bids due August 11, 2026) on fixed-price, as-needed bases with estimated aggregate quantities of 476 units over multi-year terms, where curing and finishing specifications are embedded in product-quality and dimensional-accuracy requirements. No standalone curing-mixture RFPs, IFBs, ITBs, or RFQs appear in the recent-opportunities block; curing compounds are procured as ancillary materials within concrete construction, repair, and supply contracts rather than as primary deliverables.
