MC-Special Plus Integral waterproofing of concrete using Hydrophobic pore blocking Technology forproduction of waterproof concrete.
Even in the case of excellent composition and compactnessconcrete consists of small voids. The so-called “capillary pores”(on average 13-16 percent by volume) which are due to agenerous addition of mixing water. The additional mixing wateris used to obtain sufficient compactness and workability. Owingto these capillary pores, concrete is always more or lesspervious to water or hygroscopic. As opposed to conventionalwaterproofing products, MC-Special Plus provides integralwaterproofing properties by combining two characteristics intoone specially designed product. These propertiesthat give Your Concrete the Extra Edge in Protection against water ingress are:
1. Reduction of Capillary Pores: Special additives in MC-SpecialPlus make the concrete more workable (increasesslump) at the same w/c ratio or provide a reduction in w/c at thesame workability levels. This property helps concrete achieveexcellent compactability thereby reducing capillary pores.
2. Hydrophobic Pore Blocking Mechanism: In addition toreduction of capillary pores and the DynamicSynCrystallization®, MC-Special Plus has special additives,which on one hand causes contraction of capillaries and on theother hand converts the water-absorbing capillary forces intowater repellant capillary forces due to the hydrophobic effect ofthe constituent. Thus water is pushed out of the capillary poresand the concrete is kept dry.
A combination of the properties above provide the concrete anefficient, reliable and durable waterproofing protection againstrains, ground water, moisture, dampness, humidity etc. MC-Special Plus is an integral waterproofing compound inpowder form, used for all types of concrete, requiring waterimpermeability. It conforms with IS 2645.

Advantages
Following are a few advantages of using MC- Special Plus as an additive to concrete.
- Resists water penetration and absorption.
- Makes the mix more workable (improves the slump)
- Makes the w/c ratio reduction possible.
- Does not change setting time nor adversely effect thereinforcement.
- Disperses rapidly and makes a homogenous mix.
- Free from chlorides
- Provides an efficient and durable barrier against rainwater, moisture and ground water
MC-Special Plus is easy to use, either in the concretebatching plant or in a transit mixer at site. MC-Special Plus should be added to the concrete after all other componentsof the mix have been added. Concrete should be mixed foratleast a minute after addition of MC-Special Plus. Dosageis economical at 1% by weight of cement or atleast 3kg MC-SpecialPlus per m3 of Concrete.
