• Helps prevent cold joints and cracking

Riteks LSP-2000

LSP-2000 is a highly concentrated plasticizer for low slump concrete pipes and hollow core productions. The formula produces a web on the concrete pipe that has a very smooth texture. Other low slump concrete products (concrete block and roof tile) to achieve a medium to heavy swipe with LSP-2000. LSP-2000 is a ready to use liquid that improves workability while maintaining cohesiveness and achieves fuller hydration rates of the cement in low slump concrete mixes. Features and Benefits

• Improves the surface texture and web of the pipe
• Excellent hollow core performance
• Increases early compressive strengths
• May allow reduced curing time
• Reduces cull rates
• Lubricates the mix causing less abrasion and wear on the mold parts
• Mix compacts more easily and quicker
• color is more uniform
• Increased strengths may allow reduction of cement
• Manufactured products are more dense

Riteks SRA – 157

SRA-157 is a liquid, shrinkage-reducing admixture, that can significantly decrease drying shrinkage in any Portland cement-based product. This is not expansive material, but rather functions by blocking capillaries of pore water, which is the major mechanism that causes drying shrinkage in concrete. When added to concrete at a rate of 2 % by weight of cementitious can reduce shrinkage (ASTM C 157) by up to 80% at 28 days of age and by up to 50% at one year of age. Features and Benefits

• High level of shrinkage reduction that can eliminate cracking due to drying shrinkage in restrained concrete
• Reduces potential for cracking
• Improves aesthetics
• Increases water tightness of the mix
• Improves durability of the concrete
• Reduces creep and curling of slabs
• Decreases carbonation at the surface of slabs

FormTard 50

FormTard 50 is a retarder for vertically exposed aggregate surfaces in concrete forms with nominal depth etch up to 1/4". FormTard 50 is a nonflammable, 100% V.O.C. free, paintable gel designed for easy application to vertical concrete forms.

NexCrete 1L-X

Riteks NexCrete™ 1L-X is a ready-to-use multi-range water-reducing admixture designed for use in ready-mix concrete. Based on the next generation of polycarboxylate technology, NexCrete 1L-X provides excellent early compressive strength, faster setting time characteristics and provides fluidity in mix designs with substantially reduced water content. Nexcrete 1L-X shows improved compressive strengths in comparison to commonly used Type A water reducers and faster set times than most Type F water reducers. Features and Benefits

• Faster set times- works well with slower setting cements
• Increased productivity
• Enhanced concrete durability

NexCrete ES

Riteks NexCrete™ ES is a normal setting multi-range water-reducing admixture for concrete utilizing next generation polycarboxylate technology. It is designed to facilitate the placing and finishing of ready mixed concrete that is highly flowable and workable for extended periods of time with normal setting characteristics. By varying the dosage rate, NexCrete™ ES can be used as a normal, mid-range and high-range water-reducing admixture. Feature and Benefits

• Improves the quality of concrete by decreasing water cementitious ratio
• High durability and increased density
• Reduces damage caused by freezing and thawing
• Reduces water content needed for a given workability
• Reduces surface bleeding, cracking, creep, and shrinkage
• Maintains slump life during extended mixing times
• Improves bond strength to the steel
• Reduces permeability and salt penetration

Riteks WATERPEL-S

WATERPEL-S is a multi-component, liquid water repellant admixture based on a new technology that provides long-lasting resistance to water penetration by reacting to form a very effective water resistant network throughout manufactured concrete products. When incorporated properly in concrete masonry units, WATERPEL-S has superior water repellency performance based on NCMA TEK 19, spray bar test and ASTM E514 wind driven rain test. Features and Benefits

• Less maintenance and moisture damage due to integral water repellency
• Inhibits water transmission through hardened cast-in-place concrete
• Less penetration at the surface reduces costs of paint required
• Improves color trueness and consistency
• Reduces mildew and mold growth
• Enhances texture
• Improves aesthetics and appearance
• Controls and reduces efflorescence

Riteks ES-2000

ES-2000 is specially formulated for cost efficient production of concrete masonry and pipe units. It has the ability to aid in the dispersion of cement particles to promote better early strengths. Masonry and pipe units manufactured using ES-2000 have a better appearance (medium to heavy swipe depending on materials) and are less abrasive on mold equipment. ES-2000 may be used wherever increased and improved masonry production is required. It is particularly useful in:

• Concrete block or brick
• Dry-cast concrete pipe
• Paving stones
• Specialty landscape units
