# Tensile Strength Test of Cement | Lab Test & Advantages

Table of Contents

** 1. Introduction **

Tensile Strength Test of Cement is utilized to have an indirect indication of compressive strength of cement. It is at present normally utilized for the rapid hardening cement.

** 2. Tensile Strength Test of Cement **

The aim of this test is to determine the tensile strength of the cement.

** 2.1. Apparatus Required **

a. Standard briquette mold

b. Cement

c. Water

d. Sand

** 2.2. Procedure **

This test is conducted as follows:

**a.** The tensile strength test is carried out by fracturing six briquettes made of cement mortar in the ratio of 1:3 using standard sand and test cement.

**b.** An average of six results is treated as the **tensile** strength of cement.

**c.** The percentage of water by weight of cement required to make the cement mortar is given by the relation (P/5+2.5), where P is a percentage of water required to make cement paste of normal consistency.

**d.** Cement mortar prepared in this way is filled in the standard briquette mold and cured for 24 hours at a temperature of 25-29° C and relative humidity of 90%.

**e.** The test is carried out for 3 days, 7 days, and 28 days. During the test, the load is to be applied uniformly at the rate of 35 kg/cm² or 3.50 N/mm².

**f.** The tensile stress at the end of 3 days should not be below 20 kg/cm² or 2 N/mm² and that at the end of 7 days should not be below 25 kg/cm² or 2.50 N/mm², 28 days should not be below 45 kg/cm² or 4.50 N/mm².

** 2.3 Precautions **

1. Cement mortar should be prepared in a suitable proportion.

2. Standard Briquette Mold should be cleaned properly.

3. Use gloves and apron while preparing Cement mortar.

** 3. Advantages **

1. It helps us to determine the tensile strength of the Cement.

2. It helps to know for which structure, cement can be use or not.
