Compressive Strength Test of Concrete
कंक्रीट का संपीडन सामर्थ्य परिक्षण
[I.S: 1199-1959]
- उद्देश्य(Object):-
कंक्रीट की सम्पोडन सामर्थ्य ज्ञात करना (घन परीक्षण)|
- सिद्धान्त(Theory):
सादा सीमेन्ट कंक्रीट सम्पीडन में पर्याप्त सामर्थ्य रखती है, परन्तु इसकी तनन सामर्थ्य काफी कम होती है। (सम्पीडन सामध्ये के दसवें भाग से भी कम)। अत: सादा सीमेंट कंक्रीट का प्रयोग सम्पीडन अवयवों के लिये ही किया जाता है। उच्च साम्पोडन सामयं वाली कंक्रीट चिरस्थायों होती है और इसके अन्य गुण भी उत्तम होते हैं। अपघर्षण प्रतिरोध, कंक्रीट को सम्पीडन सामय के साथ-साथ बढ़ता है। अत: कंक्रीट की गुणता की जाँच के लिये इसका सम्पीडन सामर्थ्य परीक्षण किया जाता है।
कंक्रीट की सम्पीडन सामर्थ्य परीक्षण के लिये, इसके मानक घन (अथवा सिलिण्डर) प्रतिदर्श डाले जाते हैं और उनको निर्धारित अवधि (7 दिन व 28 दिन) के पश्चात् सम्पीडन जाँच मशीन द्वारा जाँच की जाती है।
M-15 ग्रेड की कंक्रीट की 150 mm धन की 28 दिन की तराई के बाद प्रारम्भिक परीक्षण सामर्थ्य 20 N / mm तथा स्थलीय परीक्षण सामर्थ्य 15 N mm से कम नहीं होना चाहिये।
परीक्षण के लिये 100 min का धन (Cube) भी बनाया जा सकता है अथवा 150 mm व्यास का 300 mm ऊँचाई वाला सिलिण्डरनुमा प्रतिदर्श भी मान्य है, परन्तु इसकी सामर्थ्यं, घन की सामर्थ्य का 0.8 हो जाती है।
- सामग्री(Material):-
अवपात परीक्षण के लिये तैयार की गयी कंक्रीट में कम से कम 3 cube (घन )अवश्य डालें।
- उपकरण (Apparatus):-
Compressive Strength Test
- सम्पीडन परीक्षण मशीन, क्षमता 100 टन।
- 150 mm माप के घन सांचे (Cube Mould)।
- करनी।
- कुटाई छड़-16 mim व्यास, 600 mm लम्बाई, एक सिरा गोलीनुमा नोंकदार (Bullet Rounded) हो।
- विधि(Method):-
सुधट्य कंक्रीट को 50 mm की मोटी परतों में साँचे में भरे और प्रत्येक परत की कुटाई छड़ से 25 बार अच्छी तरह कुटाई करें।प्रत्येक आघात में कुटाई छड़ नीचे की परत तक धंस जानी चाहिये। संहनन क्रिया कम्पन मशीन द्वारा भी सम्पन्न की जा सकती है, परन्तु कंक्रीट का घोल कम्पनों के कारण साँचे से बाहर नहीं गिरना चाहिये।कंक्रीट भरने के बाद साँचो को (27 °C ± 3 °C )तापमान पर 24- ! घण्टों तक पड़ा रहने दें। (1)उपरोक्त अवधि के बाद प्रतिदर्श को साँचे से निकाल कर साफ पानी में डाल दें।परीक्षण काल तक प्रतिदर्श को पानी में पड़ा रहने दें। पात्र में तराई का पानी प्रति सप्ताह बदले रहे।निर्धारित अवधि (7 दिन व 28 दिनो) के पश्चात् प्रतिदर्श को पानी से निकाल लें और अच्छी तरह पोछ लें(एक पारी में कम से कम तीन प्रतिदर्श की जांच करके औसत परिणाम लिये जाते हैं ) ।प्रतिदर्श को परीक्षण मशीन में सैट करे और इस पर धीरे धीरे 14 N/mm2– प्रति मिनट की दर से दाब लगायें और तब तक लगाते रहें, जब तक प्रतिदर्श टूट न जाये।जिस भार पर प्रतिदर्श विफल होता है, नोट करें |
- प्रेक्षण (Observation):-
| CONCRETE COMPRESSIVE STRENGTH TEST | ||||
| Sr. | Particular | I | II | III |
| 1 | कंक्रीट की ग्रेड = …. | |||
| 2 | निर्दिष्ट सामर्थ्य = ….. N/mm2 | |||
| 3 | घन का विवरण | |||
| 4 | परिक्षण के समय घन की आयु =….. | |||
| 5 | प्रतिदर्श का सतही क्षेत्रफल (A)=…….mm2 | |||
| 6 | घन के विफल होते समय भार (P)= ……. | |||
| 7 | घन की संपीडन सामर्थ्य (P/A) = … N/mm2 | |||
- परिणाम(Result):-
COMPRESSIVE STENGTH= …….N/mm2
- सावधानियाँ(Precautions):-
- प्रतिदर्श पर भार समान दर से केन्द्रित लगाये। उत्केन्द्रता के कारण गलत परिणाम उपलब्ध होते हैं |
- जांच के समय तक प्रतिदर्श पानी में डूबा रहना चाहिये। सूखे प्रतिदर्श पर परोक्षण न करें।
