Grouting can be done using non-shrink
cementitious structural grout using products
These products are cementitious, structural grout. It
has a blend of portland cement, graded aggregates and additives. It is versatile
and can be prepared to be of flowable or pumpable consistency by adding the
required amount of clean water. This free flowable grout can be used in gap
width of minimum 10mm.
This product is used in precision
grouting of heavy machinery base plates, compressors, generators, and other
equipment demanding high strength properties. It is used for grouting of anchor
bolts and prefabricated concrete panels. B 30 is also suitable for general bore
packing and void filling requirements.
The properties are:-
Water / Powder Ratio: Pourable consistency
0.16%, Flowable consistency 0.17%, Free flow consistency 0.18%; Flow:
190 - 220 mm; Time for expansion — Start:
15 minutes; Finish: 2 hours; Fresh wet density Approximately : 2280kg/m³
depending on actual consistency used; Expansion
characteristics: An expansion of 2 - 4% overcomes plastic settlement in the unset material; VOC
Content: 5.85 g/L; Compressive strength Water / Powder Ratio: 0.18% BS : 6319
(Part 2): 28 days 66 N/Sqmm; Flexural strength BS : 6319 (Part 3): 28 days 10
N/Sqmm; Tensile strength BS : 6319 (Part 1) ; 28 days 3.7 N/mm²; Pull out bond
strength: 7 days 17 N/Sqmm, 28 days 24 N/ N/Sqmm; Modulus of Elasticity ASTM-D 469: 94 40000 N/Sqmm

In case, if required, base plate
grouting can be done by using non – cementitious structural grout to avoid the
curing process and time. Some of the non – cementitious structural grouts for
base plate anchoring are as follows:
