1. INTRODUCTON
In worldwide, concrete is the efficient and most ordinarily used construction material these days with
well-known combination proportion of cement, water and aggregates. Th
products like rice husk ash (RHA) and ash area unit is build as a partial replacement of cement. By
using these waste materials we tend to will conserve the usage of natural resources. RHA is an
agricultural by-product coming bac
extremely reactive pozzlana. It is hazardous to surroundings if not dispose properly. The disposal of
these waste materials creates several environmental issues. Proper utilization of thi
will defend the surroundings from greenhouse emission.

effects on concrete behaviour made from partial replacement of cement in different ratios with Rice
Husk Ash at totally different proportions.
2. MATERIALS USED
2.1. CEMENT
Cement used in this experimental work is of 53 grade of standard Portland cement (OPC) orthodox to
IS: 12269 (Part1)-1987. It was made by heating stone and clay or different appropriate raw materials
along. This material is rich in metallic element sulphate
2.2. RICE HUSK ASH
Locally available river sand satisfying requirement of IS: 383-1980Specific gravity is 2.58
2.3. COARSE AGGREGATE
Crushed angular stones of 20mm size are used as a coarse aggregate whose specific gravity is 2.86
2.4. FINE AGGREGATE
The fine aggregate was used for making concrete is river sand and it must be clean and should not
contain any alkali.
2.5. WATER
Water is an important ingredient for concrete. Normal Tap water was used.
3. METHODOLOGY
3.1. MIX DESIGN FOR CONCRETE
The mix design was done from recommended IS: 10262-1982. The concrete mix proportion was
1:1.35:2.82 by weight. Six mix proportions were done using several percentages of 0, 5, 10, 15, 20 and
25 RHA.
3.2. CASTING
A total of 36 specimens of size 150mm*150mm*150mm are casted and left for 24 hours.
3.3. CURING
In this process concrete cube it extracted for the mould after 24 from casting and treated with water for
a period of 7 to 28 days.
3.4. TEST PROCEDURE
The concrete is casted in 36 cube moulds of size 150 mm x150mm×150mm, 36 beam moulds of size
100mmX100mmX500 mm and 36 cylindrical moulds of 300 mm height and 150 mm dia. After 24
hours the specimens are submerged in water. The compressive test is done after the completion of
curing period i.e., 7-28 days.
4. RESULTS AND DISCUSSION
4.1 STRENGTH FOR 7 AND 28 DAYS
The tests for compression strength, split tensile strength and flexural strength are conducted as per
Indian codal provisions. The readings are taken as average of 3 trails in every case. The results square
measure taken from experimental investigations are showed in tables and premeditated in graphs as
are represented in [Table 1]

improvement up to replacement of 10% in all ages. Both concrete mixes at 100% rice husk ash attains
three to 100% increase in compressive strength. There is reduction in compressive strength for Rice
husk ash levels of 15 to twenty in each seven and twenty eight days as shown in [Figure 1]

4.3 SPLIT TENSILE STRENGTH:
Partial cement replacement by rice husk ash showed in concrete of grade M30 grade, split tensile
strength improvement up to the replacement of 5% in all ages as shown in [Figure 2]

4.4 FLEXURAL STRENGTH:
The tests for flexural, compressive strength in concrete were conducted for the trail mix grade with
various percentages with a mean frequency of 5% from 0 to 25%at the selected age i.e.7 and 28days.
With rice husk ash content of 10% there is significant increase in Flexural strength of the Concrete
after the completion of curing period i.e., 7-28 days as shown in [Figure 3]

5. CONCLUSION
Based on higher than study the subsequent observations ar created on partial cement replacement by
RHA in which many tests performed to ascertain the performance of rice husk ash fulfilling the
conditions of partial cement replacement material may be terminated by the subsequent points:
1. At the initial ages, as replacement level of RHA increases the compressive strength increases, here after
split tensile strength as well as flexural strength also increases simultaneously.

2. The optimum strength is obtained at the level of 10 % of OPC replaced by RHA.
3. Using RHA as replacement of OPC in concrete, the emission of pollutant and greenhouse gases
arereduced up to a maximum extent to a limited level.
4. There was a significant improvement in Compressive strength of the composition mentioned with rice
husk ash content at 10% for the design mix at different ages i.e. 7-28 days.
5. The increase in Flexural strength was in order of 1.85% to 8.88% at the age of 7 and 28 days
