Abstract-In this paper an experimental study was made on the effects of using Rice Straw Ash (RSA) as a partial replacement of cement in mortar. Control specimens with ordinary Portland cement (OPC) was made and in other specimens cement were replaced with 5%, 10% and 15% of RSA by weight of cement. Locally available rice straw was burnt to ash in uncontrolled manner in the earthen oven used by the rural people for cooking purpose, which were used in this study. The setting times and compressive strength of that mortar mix using RSA at different percentage of cement replacement was investigated and compared with the control specimen. The tests results obtained shows that setting times are delayed with increased amount of cement replacement and there is enhancement of strength of mortar with certain quantity of replacement of cement with RSA which will lead to reduction of construction cost.

“….From the experiments conducted, it was concluded that, except for the compressive strength of the sample containing silica-wadi mixture, the compressive, flexural and tensile strength of the specimens increased steadily when the percentage of WSA increased. From SEM analysis it was inferred that, when compared to reference samples, the autoclaved specimens that contain 7.3% WSA contained more amount of hydration products (C-S-H) [51].

Concrete is one of the most popular construction materials in the present world. Cement is the binding material used in concrete and its production requires large quantity of natural raw materials and generates enormous volume of greenhouse gases like CO2 . In developing and under developed countries, the primary sector forms the crucial part of the economy. The management of waste generated from agricultural sector is becoming a major concern due to their negative impact on the environment. Under this scenario, several researchers have developed supplementary cementitious materials (SCMs) from these by products that can be used as a cement replacing material in concrete. Many of these materials have shown great performance and they enhanced the fresh and hardened properties of concrete. This paper is aimed at reviewing the performance of various SCMs from agricultural waste materials. Reviewing such materials helps to identify and develop new materials

“…In the experiment process, when the test machine was loaded to the critical point, the test piece appeared tiny cracks, when the loading exceeded a certain time limit, as the external load value increased slowly, the test piece rattled and completely lost its bearing capacity. The flexural damage of the test piece was mainly the crack penetration and caused damages [13][14][15][16]. It can be seen from Table 5 that as the proportion of straw ash increased, the flexural and compressive strength of cement mortar at 7d and 28d both showed a decreasing trend.…”

This paper mainly explores the strength and performance of rice straw ash cement mortar. Firstly, the straw ash was obtained through high-temperature calcination, and the ash formation rate was measured. Then, the straw ash was rinsed with clean water and mixed into cement mortar test pieces. According to the mass ratio of cement in the test pieces, the proportion of straw ash were determined as 5 %, 10 %, 15 % and 20 %, respectively. Next, the following properties of each test piece were measured, including water absorption rate, 3d and 28d flexural strength and compressive strength. On this basis, the flexural strength and compressive strength were fitted and correlated with the proportion of straw ash. The fitting formulas and correlation functions proposed in this paper lay a theoretical basis for the engineering application of straw ash cement mortar.
