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]

4.2 COMPRESSIVE STRENGTH:

Partial cement replacement by RHA showed in M30 grade concrete, compressive strength

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]

Figure 1 Compressive strength of concrete (N/mm2)

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
