CONPROOF RMC ADMIX 88
- Add waterproofing to ready mix
- Waterproofing in transit mixer
- Basement and roof slabs
- Hydration cracking in concrete
CONPROOF RMC ADMIX 88 is a high-performance, water-reducing, crack-resistant waterproofing free-flow admixture specifically designed for ready-mix concrete operations. Added to the transit mixer at site — 100ml per 50kg bag of cement, or 4.2–5 litres per standard 6m³ load — it reduces hydration cracking, improves workability and cohesiveness, eliminates efflorescence, and strengthens the bond between concrete and steel. For water retaining structures, basements, roof slabs, screeds, bathrooms and external plaster in ready-mix concrete applications.

Where to use CONPROOF RMC ADMIX 88: waterproofing admixture for ready mix concrete
CONPROOF RMC ADMIX 88 is a waterproofing admixture for ready mix concrete, a water-reducing, free-flow liquid designed for ready-mix operations. It is poured into the transit mixer at site, where it reduces hydration cracking and improves workability and cohesiveness. This crack resistant admixture also strengthens the bond between concrete and steel.
Ready-Mix Concrete (Transit Mixer)
Add 4.2–5 litres per 6 cubic metre load and rotate 3–4 minutes.
Water Retaining Structures
A waterproofing admixture for concrete that has to hold water.
Basements
Reduces hydration cracking in basement concrete.
Roof Slabs & Screeds
Improves workability and cohesiveness of slab and screed mixes.
Bathrooms & Toilets
Added to the gauging water for wet-area mortar and concrete.
External Wall Plaster
For cement-sand plaster mortar, mixed as usual after dosing.
Swimming Pools & Tanks
Strengthens the bond between concrete and steel in water-holding structures.
Site-Batch Concrete
Stir 100 ml into the gauging water for one bag of cement.
For waterproofing in transit mixer at site, add 4.2–5 Ltrs to a 6 cubic metre load, or 100 ml per 50 kg bag of cement. It is an RMC waterproofing admixture supplied in 1, 5, 20 and 210 Ltrs packs with a shelf life of 24 months, stored in a cool and dry place in unopened containers. After adding it, rotate the mixer continuously for 3–4 minutes before unloading the concrete.
Armstrong Chemicals supplies CONPROOF RMC ADMIX 88 to sites across Telangana, Andhra Pradesh, Karnataka, Kerala and Tamil Nadu, including Hyderabad, Vijayawada, Bengaluru, Kochi and Chennai.
Why CONPROOF RMC ADMIX 88 works
Dosed at site
It goes into the transit mixer on arrival, so the waterproofing is added to the load you are about to pour.
Crack resistant
The admixture is formulated to reduce hydration cracking, so the concrete is less likely to crack as it hardens.
Free-flow and water reducing
It reduces the water needed and improves workability and cohesiveness, so the concrete flows and places more easily.
100ml Per Bag. 4.2–5L Per Load.
A water-reducing, crack-resistant waterproofing free-flow admix added directly to the RMC transit mixer at site — no batching plant changes, no pre-mixing, no extra weighing.

Site dosing calibrated to standard RMC loads — 4.2–5 litres per 6m³ mixer, rotate 3–4 minutes, unload. No batching plant modifications required.
Water Reducing + Crack Resistant
Reduces hydration within fresh concrete to minimise crack formation, improves workability and cohesiveness, and reduces bleeding and segregation.
6m³ Transit Mixer Load — Verified Method
Water Reducing. Crack Resistant. Site-Ready.
One admix — the only one in the Armstrong range with a verified transit mixer dosing calculation.
Transit Mixer Ready
Engineered for RMC operations — add 4.2–5L per 6m³ load directly at the pour site, rotate 3–4 minutes, unload. No batching plant modifications needed.
Water Reducing + Crack Resistant
Reduces hydration within fresh concrete to minimise crack formation; improves workability and cohesiveness; reduces bleeding and segregation.
Site-Batch Compatible
Also suitable for site-batch cement mortar and concrete at 100ml per 50kg bag — the same product covers both RMC and site-mixed applications.
Efflorescence Resistant
Eliminates efflorescence and improves bond strength between concrete and steel reinforcement — high durability performance from a single liquid admixture.
How to Use
Arrive at site with the RMC load in the transit mixer
Add 4.2–5 litres of CONPROOF RMC ADMIX 88 to the mixer for a 6 cubic metre load
Rotate the mixer continuously for 3–4 minutes
Unload the concrete at the specified pour location
Site-batch alternative: add 100ml of CONPROOF RMC ADMIX 88 to the gauging water for one 50kg bag of cement; stir; mix as usual
Applicable Areas

CONPROOF LW 200 is an integral waterproofing admixture for concrete and cement mortars, containing a blend of hydrophobic particles, lignosulphonates and proprietary chemicals that contract capillaries and make concrete denser and more watertight. Compliant with IS 2645-2003 and corrosion-resistant to JIS: Z 1535 (modified). Improves workability, cohesiveness and water reduction — uniform waterproofing throughout the mix from a single liquid dose. Free from sulphates; chloride content less than 0.1%.
View DetailsCONSPLAX 411 R is a chloride and sulphate-free concrete plasticizer and water reducing agent, compliant with IS 9103-1999. Formulated after extensive research, it lubricates harsh mixes, increases cohesiveness and plasticity, and reduces the water-cement ratio without loss of workability — producing completely watertight, more durable concrete. Delivers a 40% increase in durability against sulphate salts, seawater and aggressive waters. Used extensively in mass concrete works — dams, barrages, canal lining, port projects — and all concrete structures requiring improved workability.
View DetailsROOFPLAST SP 45 is a high range early strength super plasticiser and water reducing admixture based on modified sulphonated naphthalene polymers, compliant with IS 9103-99 (Amended 2003), BS-5075 Part 3 and ASTM-C-494 Type G. It reduces water-cement ratio by 20–30% without loss of slump, producing high density, cohesive concrete with reduced permeability and improved surface finish. Provides 4–5 hours of retardation to avoid cold joints in large concrete pours. Ideal for M-30 and above, high early strength, precast, ready-mix and pumped concrete. Non-toxic, non-flammable, chloride-free.
